• Predict heavy metal concentrations in crops based on samples taken from individual plants.

• Predict soil nutrient levels (nitrogen, phosphorus, potassium, and so on) and other indicators (such as electrical conductivity) in order to study their relationships to crop yield and prescribe precise amounts of fertilizer for each location in the field.

• Meteorological applications include prediction of temperatures, rainfall, and associated variables (such as acid rain).

Density analysis takes known quantities of some phenomenon and creates a density map by spreading these quantities across the map. You can use this function, for example, to show concentrations of lightning strikes or tornadoes, access to health care facilities, and population densities.

This function creates a density map from point or line features by spreading known quantities of some phenomenon (represented as attributes of the points or lines) across the map. The result is a layer of areas classified from least dense to most dense.

For point input, each point should represent the location of some event or incident, and the result layer represents a count of the incident per unit area. A larger density value in a new location means that there are more points near that location. In many cases, the result layer can be interpreted as a risk surface for future events. For example, if the input points represent locations of lightning strikes, the result layer can be interpreted as a risk surface for future lightning strikes.

For line input, the line density surface represents the total amount of line that is near each location. The units of the calculated density values are the length of line-per-unit area. For example, if the lines represent rivers, the result layer will represent the total length of rivers that are within the search radius. This result can be used to identify areas that are hospitable to grazing animals.

Other use cases of this tool include the following:

• Creating crime density maps to help police departments properly allocate resources to high crime areas.

• Calculating densities of hospitals within a county. The result layer will show areas with high and low accessibility to hospitals, and this information can be used to decide where new hospitals should be built.

• Identifying areas that are at high risk of forest fires based on historical locations of forest fires.

• Locating communities that are far from major highways in order to plan where new roads should be constructed.

## create_image_collection¶

arcgis.raster.analytics.create_image_collection(image_collection, input_rasters, raster_type_name, raster_type_params=None, out_sr=None, context=None, *, gis=None, future=False, **kwargs)

Create a collection of images that will participate in the ortho-mapping project. Provides provision to use input rasters by reference and to specify image collection properties through context parameter.

The function can also create hosted imagery layers in ArcGIS Enterprise and ArcGIS Online from local raster datasets by uploading the data to the server. A collection can be created from multiple input rasters.

For this functionality to work on ArcGIS Online, Azure library packages for Python (Azure SDK for Python - azure-storage-blob: 12.1<= version <=12.8) needs to be pre-installed. Refer https://docs.microsoft.com/en-us/azure/developer/python/azure-sdk-install

 Argument Description image_collection Required, the name of the image collection to create. The image collection can be an existing image service, in which the function will create a mosaic dataset and the existing hosted image service will then point to the new mosaic dataset. If the image collection does not exist, a new multi-tenant service will be created. This parameter can be the Item representing an existing image_collection or it can be a string representing the name of the image_collection (either existing or to be created.) input_rasters Required, the list of input rasters to be added to the image collection being created. This parameter can be any one of the following: List of portal Items of the images An image service URL Shared data path (this path must be accessible by the server) Name of a folder on the portal The function can create hosted imagery layers on enterprise and AGOL from local raster datasets by uploading the data to the server. raster_type_name Required string. The name of the raster type to use for adding data to the image collection. Choice list: [ “ASTER”, “DMCII”, “DubaiSat-2”, “GeoEye-1”, “GF-1 PMS”, “GF-1 WFV” “GF-2 PMS”, “GRIB”, “HDF”,”IKONOS”, “KOMPSAT-2”, “KOMPSAT-3”, “Landsat 1-5 MSS” “Landsat 4-5 TM”, “Landsat 7 ETM+”, “Landsat 8”, “NetCDF”, “Pleiades-1” “QuickBird”, “RapidEye”, “Raster Dataset”, “Sentinel-2”,” SkySat” “SPOT 5”, “SPOT 6”, “SPOT 7”, “Tiled Imagery Layer”, “UAV/UAS”, “WordView-1” “WordView-2”, “WordView-3”, “WordView-4”, “ZY3-SASMAC”, “Aerial”, “ScannedAerial”, “ZY3-CRESDA”] Example:“QuickBird” raster_type_params Optional dict. Additional raster_type specific parameters. The process of add rasters to the image collection can be controlled by specifying additional raster type arguments. The raster type parameters argument is a dictionary. The dictionary can contain productType, processingTemplate, pansharpenType, Filter, pansharpenWeights, ConstantZ, dem, zoffset, CorrectGeoid, ZFactor, StretchType, ScaleFactor, ValidRange Please check the table below (Supported Raster Types), for more details about the product types, processing templates, pansharpen weights for each raster type. Possible values for pansharpenType - [“Mean”, “IHS”, “Brovey”, “Esri”, “Mean”, “Gram-Schmidt”] Possible values for filter - [None, “Sharpen”, “SharpenMore”] Value for StretchType dictionary can be as follows: “None” “MinMax; ; ” “PercentMinMax; ; ” “StdDev; ” Example: {“StretchType”: “MinMax; ; ”} Value for ValidRange dictionary can be as follows: “, ” Example: {“ValidRange”: “10, 200”} Example:{“productType”:”All”,”processingTemplate”:”Pansharpen”, “pansharpenType”:”Gram-Schmidt”,”filter”:”SharpenMore”, “pansharpenWeights”:”0.85 0.7 0.35 1”,”constantZ”:-9999} out_sr Optional integer. Additional parameters of the service. The following additional parameters can be specified: Spatial reference of the image_collection; The well-known ID of the spatial reference or a spatial reference dictionary object for the input geometries. If the raster type name is set to “UAV/UAS”, the spatial reference of the output image collection will be determined by the raster type parameters defined. context Optional dict. The context parameter is used to provide additional input parameters. Syntax: {“image_collection_properties”: {“imageCollectionType”:”Satellite”},”byref”:True} Use image_collection_properties key to set value for imageCollectionType. Note The “imageCollectionType” property is important for image collection that will later on be adjusted by orthomapping system service. Based on the image collection type, the orthomapping system service will choose different algorithm for adjustment. Therefore, if the image collection is created by reference, the requester should set this property based on the type of images in the image collection using the following keywords. If the imageCollectionType is not set, it defaults to “UAV/UAS” If byref is set to ‘True’, the data will not be uploaded. If it is not set, the default is ‘False’ upload_properties key can be used to control specific upload parameters when trying to create hosted imagery layers in ArcGIS Online from local raster datasets. Available options: “maxUploadConcurrency”: Optional integer. Maximum number of parallel connections to use for large uploads (when individual file/blob size exceeds 64MB). This is the max_concurrency parameter of the BlobClient.upload_blob() method. (The default is 6) “maxWorkerThreads”: Optional integer. Maximum number of threads to execute asynchronously when uploading multiple files. This is the max_workers parameter of the ThreadPoolExecutor() class. (The default is None) “displayProgress”: Optional boolean. If set to True, a progress bar will be displayed for tracking the progress of the uploads to user’s rasterstore. (The default is False) Example: {“upload_properties”:{“maxUploadConcurrency”:8, “maxWorkerThreads”:20, “displayProgress”:True} } The context parameter can also be used to specify whether to build overviews, build footprints, to specify pixel value that represents the NoData etc. Example: {“buildFootprints”:True, “footprintsArguments”:{“method”:”RADIOMETRY”,”minValue”:1,”maxValue”:5, “shrinkDistance”:50,”skipOverviews”:True,”updateBoundary”:True, “maintainEdge”:False,”simplification”:None,”numVertices”:20, “minThinnessRatio”:0.05,”maxSliverSize”:20,”requestSize”:2000, “minRegionSize”:100}, “defineNodata”:True, “noDataArguments”:{“noDataValues”:[500],”numberOfBand”:99,”compositeValue”:True}, “buildOverview”:True} gis Keyword only parameter. Optional GIS. The GIS on which this tool runs. If not specified, the active GIS is used. future Keyword only parameter. Optional boolean. If True, the result will be a GPJob object and results will be returned asynchronously. folder Keyword only parameter. Optional str or dict. Creates a folder in the portal, if it does not exist, with the given folder name and persists the output in this folder. The dictionary returned by the gis.content.create_folder() can also be passed in as input. Example:{‘username’: ‘user1’, ‘id’: ‘6a3b77c187514ef7873ba73338cf1af8’, ‘title’: ‘trial’}

Function evaluates changes in pixel values over time using the Landsat-based detection of trends in disturbance and recovery (LandTrendr) method and generates a change analysis raster containing the model results. Function available in ArcGIS Image Server 10.9 and higher.

 Argument Description input_multidimensional_raster Required ImageryLayer object. The input multidimensional raster. Portal Item can be passed. processing_band Optional string. The band to use for segmenting the pixel value trajectories over time. Choose the band that will best capture the changes in the feature you want to observe. If no band value is specified and the input is multiband imagery, the first band in the multiband image will be used. Example:“Band_1” snapping_date Optional string. The date used to select a slice for each year in the input multidimensional dataset. The slice with the date closest to the snapping date will be selected. This parameter is required if the input dataset contains sub-yearly data. The default is “06-30” (or June 30), approximately midway through a calendar year. Example:“06-30” max_num_segments Optional int. The maximum number of segments to be fitted to the time series for each pixel. The default is 5. Example:5 vertex_count_overshoot Optional int. The number of additional vertices beyond max_num_segments + 1 that can be used to fit the model during the initial stage of identifying vertices. Later in the modeling process, the number of additional vertices will be reduced to max_num_segments + 1. The default is 2. Example:2 spike_threshold Optional float. The threshold to use for dampening spikes or anomalies in the pixel value trajectory. The value must range between 0 and 1, where 1 means no dampening. The default is 0.9. Example:0.9 recovery_threshold Optional float. The recovery threshold value, in years. If a segment has a recovery rate that is faster than 1/recovery threshold, the segment is discarded and not included in the time series model. The value must range between 0 and 1. The default is 0.25. Example:0.25 prevent_one_year_recovery Optional boolean. Specifies whether segments that exhibit a one year recovery will be excluded. True - Segments that exhibit a one year recovery will be excluded. This is the default. False - Segments that exhibit a one year recovery will not be excluded. Example:True increasing_recovery_trend Optional boolean. Specifies whether the recovery has an increasing (positive) trend. True - The recovery has an increasing trend. This is the default. False - The recovery has a decreasing trend. Example:True min_num_observations Optional int. The minimum number of valid observations required to perform fitting. The number of years in the input multidimensional dataset must be equal to or greater than this value. The default is 6. Example:6 best_model_proportion Optional float. The best model proportion value. During the model selection process, the tool will calculate the p-value for each model and select a model that has the most vertices while maintaining the smallest (most significant) p-value based on this proportion value. A value of 1 means the model has the lowest p-value but may not have a high number of vertices. The default is 1.25. Example:1.25 pvalue_threshold Optional float. The p-value threshold for a model to be selected. After the vertices are detected in the initial stage of the model fitting, the tool will fit each segment and calculate the p-value to determine the significance of the model. On the next iteration, the model will decrease the number of segments by one and recalculate the p-value. This will continue and, if the p-value is smaller than the value specified in this parameter, the model will be selected and the tool will stop searching for a better model. If no such model is selected, the tool will select a model with a p-value smaller than the lowest p-value × best model proportion value. The default is 0.01. Example:0.01 output_other_bands Optional boolean. Specifies whether other bands will be included in the segmentation process. True - Other bands will be included. The segmentation and vertices information from the initial segmentation band specified in the processing_band parameter will also be fitted to the remaining bands in the multiband images. The model results will include the segmentation band first, then the remaining bands. False - Other bands will not be included. This is the default. Example:2 output_name Optional. If not provided, an Image Service is created by the method and used as the output raster. You can pass in an existing Image Service Item from your GIS to use that instead. Alternatively, you can pass in the name of the output Image Service that should be created by this method to be used as the output for the tool.

A value of 50 will produce essentially the same result as the Median statistic. This option is only available if the Statistics Type parameter is set to PERCENTILE or ALL. process_as_multidimensional Optional bool, Determines how the input rasters will be processed if they are multidimensional. False - Statistics will be calculated from the current slice of a multidimensional image service. This is the default.
