Introduction

The ESRI Arc/Info Grid (.asc) format is a widely used format for gridded datasets (such as DEMs and results files). The TUFLOW_to_GIS utility outputs in this file format.

Method

QGIS has native support for this format.

  1. ESRI grid (.asc) files can be directly opened in QGIS by selecting Layers >>> Add Raster Layer.
  2. Navigate to the desired file and select Open.

The opened grid will be displayed in the projection of the project. This should be set to the projection of the grids, to change the projection of the project see the Setting Project Projection page.
