Vertical Mapper Tips

Introduction

This page contains a brief introduction to the Vertical Mapper plugin to MapInfo. There are a number of TUFLOW related tasks that can be performed in Vertical Mapper (abbreviated in this wiki as VM). The Vertical Mapper tasks which are repeatedly used in creating a TUFLOW model are described below, each of these has a separate page.

Grid File Formats

A Vertical Mapper grid consists of two files: a MapInfo Table file (.tab) and a .grd (numeric grid) or .grc (classified grid). Most of the grids that are used in TUFLOW modelling are numeric grids (such as Digital Elevation Models (DEMs). At each cell in a grid, a value is stored. So for a DEM with cell resolution of 1m, each 1m x 1m cell has an elevation assigned. The Vertical Mapper Grid formats are binary format files and are only edited within the Vertical Mapper interface.
Grids created with the TUFLOW_to_GIS utility are outputted in a .asc format, this is a text file which is recognised by Vertical Mapper, Spatial Analyst and QGIS. For more information see: Importing Grids.
