Why is Topo to Raster not working?

Why is Topo to Raster not working?

Likely causes of problems with Topo to Raster There are insufficient system resources available. The algorithms used in Topo to Raster hold as much information as possible in memory during processing. This allows point, contour, sink, stream, and lake data to be accessed simultaneously.

How do I convert contour to raster in Arcgis?


  1. Navigate to System Toolboxes > Spatial Analyst Tools > Interpolation > Topo to Raster.
  2. Select the contour layer as the input feature data.
  3. Specify the location of the output surface raster.
  4. Set the output extent the same as the contour layer’s extent.
  5. Click OK. A raster layer is created from the contour.

How do you get contours from DEM in Arcgis?


  1. Start ArcMap.
  2. Load the DEMs files you want to filter.
  3. Load data in the map if necessary.
  4. On the main menu, click Customize > Toolbars > Production Contouring.
  5. Click the Create Contours button.
  6. If necessary, type a value in the Base Contour text box.
  7. Type a value in the Contour Interval text box.

Can you create a DEM from contours?

It is possible to generate a DEM from a contour line shapefile, though some methods will tend to have “stair-step” artifacts and lower spatial resolution than the original data. Adding data from other sources and pre-processing your contours can reduce these problems.

How do you do raster contours?

To create contours or isolines from a raster surface, use the Contour tool. To create contours or isolines based on a list of contour values, use the Contour List tool. To create contours from a raster surface and independently generate contours on either side of a barrier, use the Contour With Barriers tool.

How do I create a DEM layer in Qgis?

How to Create Elevation Profile in QGIS

  1. Open Profile tool plugin.
  2. Add the DEM layer using Add Layer button.
  3. Next, just draw a polyline on the QGIS map canvas where you want to create elevation profile as in figure 7.
  4. When finished the elevation profile will be appeared in the Profile tool window as in figure 8.
