None – No stretch method is applied to the layer, even if statistics exist.

Choose between one of the stretch methods available:.

In practice, this means that your layer will be visualised as a gradient of your color ramp, as opposed to the separate classes with the other method. Similarly to the classified method, ‘Stretched’ will allow you to assign colours to pixel values, but instead of a separate fixed number of classes, it takes the range of all values in your data and stretches it to fit within a data type range. Note: If you’re working with a multiband file but have selected to classify it as a single-band, you will also be able to choose which band you wish to use for classification.

Save your work and take a look at your raster layer on the map!.

You can manually adjust the range that was selected automatically and the label for each class separately, as well as adjust colors.

Define the number of classes you wish to create and click on Classify.

Anything outside of that range will not be shown on the render.

Define the range by entering the minimum and maximum pixel values.

Choose your color ramp (you can also choose to invert the colors, for example if the ramp is black-white, you can invert it to white-black).

Select the Classified rendering method – this rendering method assigns a color for each class or group of values.

A color map is useful when you want to select a color for each pixel value.įollow the steps below to classify a single-band raster: The ‘Classified’ rendering method considers the distribution of values and groups the values into the number of breaks or colors you want to display.

Classifying rasters is useful for creating thematic maps, for example showing different land use or land cover classes, or to visualise different vegetation indices. You can classify raster files based on the pixel values by choosing different rendering methods, ranges, and number of classes. If you’re working with a single-band raster, the Classification Wizard will automatically open for you to modify the appearance settings. It is not possible to switch the render type to Multiband since the file only contains one band.

When using a single-band raster file, the system will automatically recognize that the added raster is single-band, and will set the Render type accordingly. For single-band rasters, you must first choose the visualisation method before you can see the layer on the map! You can access the style settings by opening the Layer properties (double-click on the layer). Once you’ve uploaded your raster to GIS Cloud, you can add the file as a new layer to your map by choosing Add layer, and selecting the relevant file from the File Manager or your external database in Database Manager.

If you’re also looking for how to upload your rasters, or how to add a raster mosaic, check out the following guides: How to add rasters to the map?, How to add raster mosaic? Working with single-band rasters If the raster doesn’t have the projection file, it won’t fit the map. If the raster is not georeferenced, don’t forget to upload the projection file too. GIS Cloud supports these raster file types. Multiband is the default render setting, and the Single-band setting can be used with both single-band and multiband files (for example, select just one band to use for classification). Before uploading data, first, make sure to check which spatial raster files are supported. GIS Cloud currently supports multiband and single-band raster types.

Apart from using vectors (like points, lines, and polygons) on your maps, in GIS Cloud you can also add and use raster images (for example satellite or drone imagery, vegetation indices, etc.).
