MapInfo Pro Advanced supports a wide variety of interpolation methods that allow you to create continuous raster surfaces from point, line and polygon data. There are various interpolation algorithms available which provide different approaches for converting your point data into a raster. For best result you should choose an interpolation method which is appropriate for the type of input data you have and the type of raster surface you need, to perform your analysis.
MapInfo Pro Advanced supports the following input file formats for creating a raster surface:
- TAB - MapInfo TAB Files (*.tab)
- LAS - LIDAR ASPERS LAS Files (*.las) - The LIDAR point cloud data.
- LAZ - The compressed version of LAS files (*.laz)
- ASCII
- ZIP Files (*.zip, *.7z)
Limitation: CRS, if stored as a WKT string inside LAS/LAZ file (Most common for LAS/LAZ files on version 1.4 specification), cannot be read.
Interpolation Method
MapInfo Pro Advanced supports several methods to create Heatmap and surface raster from point data. These methods have been grouped into logical categories. There are categories for Heatmap, Assignment, and Interpolation. Each category has multiple options under them. When you select any method from a category, the dialog box title displays the category name instead of selected method name.
