Write Raster

Github repository: github.com/movestore/write-raster

Description

Transforms input data into a density raster (number of tracks) that can be downloaded in several GIS formats.

Documentation

The dataset is projected to an azimuthal equidistant (AEQD) CRS centered on the data, with units in metres. For each individual track, the line is rasterized into a grid of user-defined grid size (in meters) and data-related bounding box. Tracks with less than 2 positions are removed. Rasterized tracks are summed resulting in one density raster (number of tracks) that can be downloaded in the user-selected file format (raster, ascii, CDF, or GTiff).

Application scope

Generality of App usability

This App was developed for any taxonomic group.

Required data properties

The App should work for any kind of (location) data.

Input data

move2::move2_loc

Output data

move2::move2_loc

Artefacts

data_raster.***: Raster file for download in one of four possible formats:

data_raster.grd (raster) data_raster.asc (ASCII grid) data_raster.nc (netCDF) data_raster.tif (GeoTIFF)

Settings

Value of your grid size (grid): This parameter allows the user to decide on the grid cell size (in metres) that the raster shall be calculated in. One numeric value has to be entered. The default is 100000.

Raster file type (raster_type): The user can select one of four different raster output file formats: raster, ascii, netCDF or GeoTiff. The default is "raster".

Changes in output data

The input data remains unchanged.

Null or error handling:

tracks: If no track has at least 2 positions, the app logs: "No tracks with at least 2 positions in your data set. No rasterization possible." is shown.
