Importing ACSII Grid into Earthlight is a two stage process. In the first stage we have to translate the source data into GeoTIFFs. The second stage involves transforming the GeoTIFFs into Earthlight readable raster pyramids. Both stages are performed by StatMap Raster Loader.
Stage I – Translating ASCII Grid into GeoTIFFs
- Open Raster Loader.
- Click "Advanced tasks..." in the bottom-left corner of the interface
- Select "Create shaded relief, aspect and slope map..."
- Change the file filter format from GeoTIFF to ACSII Grid and navigate to the location where your ASC data is located.
- Select all files that you want to process and click 'Open'.
- Choose the directory for output dataset.
Stage II - Transforming heigh, aspect, aspect, slope and hillshade GeoTIFFs into SMPyramids
After first stage you will get four files: aspect, slope, height and hillshade. In order to process them please perform the steps 1 to 4 listed below for each of the images.
- Open Raster Loader
- Configure the source and destination fields accordingly
- For Aspect, Slope and Height select Lossless PNG format and check "Image contain values (not colours)"
- For Hillshade select Lossless PNG format
