Tutorial

In the following tutorial we will access the persistent database analysing raster and raster-time-series data. We will use the import and export features of actinia-specific process chains to process Sentinel-2A scenes with several GRASS GIS modules and export the result as GeoTiff files.

The following examples shows the REST service access using the command line tool curl1. Curl should be available on many Linux systems. However, tools like postman2 allow a more comfortable way to access actinia.

Using curl for HTTP requests

We will use the Unix shell and curl to access the REST API. First open a shell of choice (we use bash here) and setup the login information, the IP address and the port on which the actinia service is running, so you can simply change the IP and port if your server uses a different address:

export ACTINIA_URL=https://actinia.mundialis.de/api/v3
export AUTH='-u demouser:gu3st!pa55w0rd'
# other user credentials can be provided in the same way

Access to projects and mapsets in the persistent database

The following API call lists all available projects in the actinia persistent database (the -i includes the HTTP response headers):

 curl ${AUTH} -X GET -i "${ACTINIA_URL}/projects"

The output should look similar to this:

 {
   "projects": [
     "latlong_wgs84",
     "nc_spm_08"
   ],
   "status": "success"
 }

To show the region settings and the projection of the GRASS GIS standard project nc_spm_08 the following REST call must be used:

 curl ${AUTH} -X GET "${ACTINIA_URL}/projects/nc_spm_08/info"

The JSON response is the standard response of the actinia REST API. Most API calls respond using this JSON structure. The difference between API calls is the result part that is located in the JSON section with the name process_results. The response includes all steps that were executed to receive the projection information and the region information. It is located in the process_log section of the JSON response. In addition API specific information as well as the processing time are available in the response. To make the JSON response more readable you can use parsing-tools like jq.

The output should look similar to this then:

Access to raster layers in the persistent database

The modis_lst mapset of the nc_spm_08 project contains monthly MODIS land surface temperature data. The space-time raster dataset LST_Day_monthly consists of 24 raster layers covering the period from January 2015 to January 2017. We list all raster layers available in this mapset:

 curl ${AUTH} -X GET "${ACTINIA_URL}/projects/nc_spm_08/mapsets/modis_lst/raster_layers"

The response lists all raster layers of the mapset in the process_results section:

Access to raster time-series in the persistent database

Actinia supports the analysis of time-series data based on the temporal framework of GRASS GIS3, 4. A time-series dataset is available in the modis_lst mapset of the nc_spm_08 project. The time-series datatype is called space-time raster dataset (strds) named LST_Day_monthly. It consists of 24 monthly raster layers covering the period from January 2015 through December 2016.

We list all strds with the following API call:

 curl ${AUTH} -X GET "${ACTINIA_URL}/projects/nc_spm_08/mapsets/modis_lst/strds"

We receive two strds in the process_results section of the JSON response:
