First you need to extract the information of your gps to gpx format. Usually I do it by using Easy GPS the free version of ExpertGPS. Once you have the gpx file you can load it in to Qgis using GPS tools (vector/gps/gpstools).Qgis will open the gpx file and will separate waypoints tracks and routes. Then a)rightclick on the waypoints and choose save as. ...

There's no need for any fancy tools here at all. Just a decent text-editor (notepad will do if necessary) will let you turn it into a ASCII text file in a few easy steps. Process Export your data as a CSV file (Excel/LibreOffice). (If you can export it with space as the delimiter, skip step 4). This gives me for my subset of 6 squares: ...

There are many files called ASCII or GRID, it can be very confusing to work out which is which. A good text editor like Notepad++ or TextPad is invaluable in determining what you actually have. An Esri ASCII Grid will look like this: ncols 1000 nrows 1000 xllcorner 489000.000000000000 yllcorner 6679000.000000000000 cellsize ...

Use GDAL or (QGIS as suggested by Joseph) for the GPX to SHP conversion. Otherwise, there are commercial solutions such as expertGPS.

There's a great tutorial from Wichmann et al. (2012) 1 here. Using SAGA GIS to process LiDAR data and create nDSM and DTM is a 6-step procedure very easy to follow. Reference: 1- Wichmann, V.; Conrad, O.; Jochem, A.: LiDAR Point Cloud Processing with SAGA GIS. In: Hamburger Beiträge zur Physischen Geographie und Landschaftsökologie 20, S. 81-90.

The problem is that something in the stack (QGIS, GDAL, or the operating system) doesn't appear to be handling the ã character in the directory name (so Portimão becomes Portimo). That looks like a bug, which you should check isn't already filed at http://hub.qgis.org/projects/quantum-gis/issues, and if not already filed, add details. In the mean time, I'd ...

QGIS plugin: GPS Tools. (I don't remember now if you have to install this or if it's already loaded) QGIS menu: Vector | GPS | GPS Tools The GPS Tools window appears. On the 'Load GPX file' browse to the GPX file. Select the 'Waypoints' check box (you are telling QGIS what to extract from the file - one GPX file can contain all of these things, but they ...

My favorite has always been DNRGarmin from the Minnesota DNR. It is designed to work with ArcGIS but will work as a stand alone tool as well. http://www.dnr.state.mn.us/mis/gis/tools/arcview/extensions/DNRGarmin/DNRGarmin.html

Seems ok for me. In the QGIS input form, you have given a file name for the asc file. In most cases, the default file extension will be added, but this dialogue does not do it. I suggest to enter the extension always manually in this input box. The prj file contains the projection information (same as for shapefiles), while the xml contains other metadata ...

That's very odd because in creating an ESRI floating point raster, Whitebox simply changes the extension of the .tas file (Whitebox) to .flt (ESRI). They share the same basic data format so there is no need to convert anything but the accompanying header file. Given this, I just don't see how the data could be changed in the process. Have you confirmed that ...

Not sure about Minecraft but many games use grayscale bitmaps to create height maps. Basically you go take a DEM, convert it to a greyscale bitmap and replace a file in the games file system with it. Some games that I know support this include: Sim City 3000 Instruction on How to do this World In Conflict Instruction on how to do this in WICed Crysis and ...
