arcgis.raster module

The arcgis.raster module containing classes and raster analysis functions for working with raster data and imagery layers.

Raster data is made up of a grid of cells, where each cell or pixel can have a value. Raster data is useful for storing data that varies continuously, as in a satellite image, a surface of chemical concentrations, or an elevation surface.

Use arcgis.raster.analytics.is_supported(gis) to check if raster analysis is supported in your GIS.

ImageryLayer

class arcgis.raster.ImageryLayer(url, gis=None)

attribute_table(rendering_rule=None)

The attribute_table method returns categorical mapping of pixel values (for example, a class, group, category, or membership).

Arguments

measure(from_geometry, to_geometry=None, measure_operation=None, pixel_size=None, mosaic_rule=None, linear_unit=None, angular_unit=None, area_unit=None)

The result of this operation includes the name of the raster dataset being used, sensor name, and measured values. The measure operation can be supported by image services from raster datasets and mosaic datasets. Spatial reference is required to perform basic measurement (distance, area, and so on). Sensor metadata (geodata transformation) needs to be present in the data source used by an image layer to enable height measurement (for example, imagery with RPCs). The mosaic dataset or Layer needs to include DEM to perform 3D measure.

Arguments	Description
from_geometry	required Geomerty or dictionary. A geometry that defines the “from” location of the measurement.
to_geometry	optional Geomerty. A geometry that defines the “to” location of the measurement. The type of geometry must be the same as from_geometry.

temporal_profile(points=[], time_field=None, variables=[], bands=[0], time_extent=None, dimension=None, dimension_values=[], show_values=False, trend_type=None, trend_order=None, plot_properties={})

A temporal profile serves as a basic analysis tool for imagery data in a time series. Visualizing change over time with the temporal profile allows trends to be displayed and compared with variables, bands, or values from other dimensions simultaneously.

Using the functionality in temporal profile charts, you can perform trend analysis, gain insight into multidimensional raster data at given locations, and plot values that are changing over time in the form of a line graph.

Temporal profile charts can be used in various scientific applications involving time series analysis of raster data, and the graphical output of results can be used directly as input for strategy management and decision making.

The y-axis of the temporal profile displays the variable value.

The temporal profile is created based on the specific values in other dimensions, such as depth at the corresponding time value. For example, soil moisture data usually includes both a time dimension and vertical dimension below the earth’s surface, resulting in a temporal profile at 0.1, 0.2, and 0.3 meters below the ground.

For cached image services, this method represents a single cached tile for the image. The image bytes for the tile at the specified level, row, and column are directly streamed to the client. If the tile is not found, an HTTP status code of 404 .

Arguments	Description
level	required integer. The level of detail ID.
row	required integer. The row of the cache to pull from.
column	required integer. The column of the cache to pull from.
blank_tile	optional boolean. Default is False. This parameter applies only to cached image services that are configured with the ability to return blank or missing tiles for areas where cache is not available. When False, the server will return a resource not found (HTTP 404) response instead of a blank or missing tile. When this parameter is not set, the response will contain the header blank-tile : true for a blank/missing tile.

delete(raster_ids)

The Delete Rasters operation deletes one or more rasters in an image layer.

Argument	Description
raster_ids	required string. The object IDs of a raster catalog items to be removed. This is a comma seperated string. example 1: raster_ids=’1,2,3,4’ # Multiple IDs example 2: raster_ids=’10’ # single ID

The Update Raster operation updates rasters (attributes and footprints, or replaces existing raster files) in an image layer. In most cases, this operation is used to update attributes or footprints of existing rasters in an image layer. In cases where the original raster needs to be replaced, the new raster can either be items uploaded using the items parameter or URLs of published services using the serviceUrl parameter.

Argument	Description
raster_ids	required integer. The object IDs of a raster catalog items to be updated.
files	optional list. Local source location to the raster to replace the dataset with. Example: [r”<path>data.tiff”]
item_ids	optional string. The uploaded items (raster files) being used to replace existing raster.
service_url	optional string. The URL of the layer to be uploaded to replace existing raster data. The image layer will add this URL to the mosaic dataset. The serviceUrl is required for the following raster types: Image Layer, Map Service, WCS, and WMS.
compute_statistics	If true, statistics for the uploaded raster will be computed. The default is false.
build_pyramids	optional boolean. If true, builds pyramids for the uploaded raster. The default is false.
build_thumbnail	optional boolean. If true, generates a thumbnail for the uploaded raster. The default is false.
minimum_cell_size_factor	optional float. The factor (times raster resolution) used to populate MinPS field (minimum cell size above which raster is visible).
maximum_cell_size_factor	optional float. The factor (times raster resolution) used to populate MaxPS field (maximum cell size below which raster is visible).

attributes	optional dictionary. Any attribute for the uploaded raster.
geodata_transforms	optional string. The geodata transformations applied on the updated rasters. A geodata transformation is a mathematical model that performs geometric transformation on a raster. It defines how the pixels will be transformed when displayed or accessed, such as polynomial, projective, or identity transformations. The geodata transformations will be applied to the updated dataset.
apply_method	optional string. Defines how to apply the provided geodataTransform. The default is esriGeodataTransformApplyAppend. Values: esriGeodataTransformApplyAppend, esriGeodataTransformApplyReplace, esriGeodataTransformApplyOverwrite
