# Reddit update: elevation data in MapTools Converter

Source post to update:
https://www.reddit.com/r/ArxSilex_MapTools/comments/1w4552w/create_your_own_offline_map_for_exactly_the_area/

The existing post is recent and already explains the complete map/POI workflow. Editing it is clearer
than publishing a near-duplicate post.

## Recommended addition to the existing post

Insert this section before **Local, portable and open source**:

```markdown
**New: prepare elevation data for the same area**

The Converter can now import HGT/SRTM, DEM GeoTIFF, ESRI ASCII Grid and DTED elevation data—either
on its own or together with map and POI sources. ZIP archives may also contain a mixture of supported
map, POI and elevation files.

If only elevation files are loaded, the area-selection screen displays a local terrain preview with
hypsometric colours and shaded relief. You can use the same rectangles and circles as for a map, so
the terrain extract matches the area prepared for your tour or field project.

Elevation data can be exported as GeoTIFF, ESRI ASCII Grid, HGT tiles or DTED cells and then imported
into MapTools for local elevation values, profiles, hillshade, contours and terrain-based calculations.
The elevation result remains a separate file; it is not embedded in the Mapsforge `.map` file. This
means you can use only a map, only POIs, only terrain data, or any combination of them.

Version 1.5.2 includes the optimized multi-HGT GeoTIFF export introduced in 1.5.1, using geographically indexed source
tiles, parallel CPU workers and bounded buffers selected for the available memory. A low-memory path
remains available on 4 GiB systems.
```

Replace the first paragraph below **Local, portable and open source** with:

```markdown
The current public release is ArxSilex MapTools Converter 1.5.2. Portable packages are available for
Windows x64 and Linux x64 and do not require a separate Java installation. The Converter is free
software under GPL-3.0-only. The download page always offers only the latest public release.
```

Keep the existing SmartScreen, checksum, OSM attribution and download paragraphs unchanged.

## Optional short follow-up post

Use this only if the existing post should remain unchanged.

### Title

```text
Update: crop and convert offline elevation data for exactly the area you need
```

### Body

```markdown
The MapTools Converter workflow now covers terrain data as well as maps and POIs.

You can load HGT/SRTM, DEM GeoTIFF, ESRI ASCII Grid or DTED files—alone, together with `.map` and
`.poi` sources, or from a mixed ZIP archive. With elevation-only input, a local hypsometric terrain
preview with shaded relief lets you select the required area using the same rectangles and circles as
the map workflow.

Export the selection as GeoTIFF, ASC, HGT or DTED and import the result into MapTools. Terrain data
remains separate from the Mapsforge map, so map, searchable POIs and elevation data can be updated or
combined independently.

The current public version is 1.5.2. Large multi-HGT GeoTIFF jobs use geographically indexed
sources, parallel CPU processing and memory-bounded buffers, while retaining a low-memory path for
4 GiB systems.
