One other option, and I am not suggesting it is a good one for a second, is to use the raster calculator operation. I tested it on a small classified raster in MRR format and it worked. If your raster is in Vertical Mapper GRC or GeoTIFF format that is an additional unknown. You can use an expression ...

Hi Matt, The only VRT files I have to test are some TIFF images that are geolocated and warped using a VRT. They work in MapInfo Pro v21. You ought to check your MapInfo Pro Raster Preferences in the backstage area and make sure that the GDAL VRT format is enabled for processing and display. Also, ...

The key difference is that when you open a raster in v21 it keeps the file open and uses a Windows file handle. Each process only gets about 2000 file handles so if you try to open more than 2000 rasters you run out of handles. When this happens, the engine will probably crash. Also, each raster tile ...

I have been trying to come to grips with Landsat scene pre-processing. Landsat science is a constantly moving target - a spice with many tastes - a dizzying array of textures...and moments... Anyway, it is confusing and takes effort to keep abreast of. Maybe this video will help. If you want to display ...

I am pleased to announce that you can now purchase ProRaster, my new raster rendering software for MapInfo Pro, from the Microsoft Store! It currently ships in two tiers - Essential and Premium. Get started by downloading the free evaluation version - search for "ProRaster Essential Free" on the Microsoft ...

Hi Jay, You can use the raster plugin in the latest version of MapInfo Pro to create some kinds of MVR virtual rasters. However, this only covers some of the ground and there are other kinds of MVR that are undocumented. I know how to write them because I wrote the code originally. At this time, as ...

The European Space Agency released a new raster dataset last year called WorldCover. It is a 10-meter resolution global land cover classified raster derived from Sentinel-1 and Sentinel-2 satellite multispectral data. I downloaded the dataset from AWS S3 and took a look at it in MapInfo Pro and ProRaster. ...

I have prepared a series of four videos and articles that explain modern raster technology. My motivation is to shed some light on the raster engine that sits inside MapInfo Pro, which I helped design and build. These are not "How to..." videos - they are "What's under the hood" videos. In a sense, ...

A little update to this: I downloaded a portion of the dataset, but when you download the entire dataset it behaves differently. To use the same MVR trick on the full dataset you need to add some driver preference directives to force the TIFF driver in MapInfo to load the raster a certain way. The ...

Hi Jane, There is a mechanism to load a GeoTIFF file as a Classified file. What you need is a GDAL PAMDataset auxiliary file (otherwise known as a raster attribute table or RAT file). If you have a TIF file called "LCM.TIF", then this auxiliary file would need to be called "LCM.TIF.AUX.XML". It would ...

Hi Peter, You could get LASTools from here and run the LASINFO tool that is included. Open a CMD window and do something like "lasinfo *.las" and it will spew out information. If the gridding stops it is probably failing to open the LAS file, so it might be corrupted or not a real LAS file or something. ...

If you want to use QGIS to display or process MRR format rasters, or you want to share MRRs that you have created with clients or colleagues who use QGIS, you (the QGIS user) will need to install the MRR GDAL driver. I have recently gone through this process and I have shared an article and a video on ...

I posted a couple of videos recently demonstrating how easy it is to build Ground surface rasters (DTM) from LIDAR survey data in MapInfo Pro 2021. I used data acquired on the Central Coast in Australia and also created a bathymetry raster surface for my local coastline. The second LiDAR processing ...

MapInfo Pro comes with simple but very powerful LiDAR gridding capabilities. I recently had cause to grid two different LiDAR surveys - to create a Ground surface raster in the first case, and to create a Ground & Bathymetry surface raster in the second. The data covers my hometown - the Central Coast ...

Yes, you need a Microsoft Account to install apps on the Microsoft Store. For future reference, if you can't find an app, or you found it but can't install it, here are some reasons why you might not see it: Your PC isn't authorized to use Microsoft Store apps. You'll need to sign in to the app ...

Thanks for trying! I just checked the Microsoft Store and it indicates the app is available in 241 countries including Germany. Also, several people have acquired and/or installed the app in Germany. So I am guessing it is there... somewhere... I am not sure how to help you further. Maybe search based ...

Hi Stephan, You would be just the right man to review my "Projection Explorer" app on the Windows Store! It is just a demo, and it is free. Download it from the Windows Store by searching for "Projection Explorer" by Roberts Geospatial Engineering. It is based on the MapInfo PRJ file and allows ...
