kmap Files

What's fixed

Smaller maps, built faster. Less is kept out at sea, and a name the map's code page cannot draw gets a readable stand-in, the way mkgmap itself writes one. Contours, elevation reading and extract reading now run on vector code on every processor, AVX2 included.

• Downloads: each file is fetched once even across separate kmap runs, a damaged or replaced extract is never built from, and a dropped download picks up where it stopped on every platform. Clearing the cache removes only kmap's own files.
• Elevation: a tile that failed to download is no longer taken for sea.
• A TYP file is read in the encoding it declares, and odd but valid TYP files load.
• kmap recover writes the same sheet on every run.
• 2 builds of the same region at once are refused instead of colliding, an earlier output is never lost, and builds that share a style keep their hidden features apart.
• Ctrl+C, a full disk or a broken extract no longer leave half-written files in split, road repair or tool installs, and the terminal is left clean after a kill.
• The command line refuses malformed numbers and stray arguments instead of guessing.
• Fixes in the pixel editor: undo and night pictures.

Upgrading

Install over the top. On Debian and Ubuntu sudo apt install ./kmap_1.7.4_<arch>.deb; on other Linux unpack the archive and put kmap on your PATH; on Windows run the installer; on macOS replace the app. Profiles, styles and cached downloads stay put.

Which file

Windows 10 1803 or later, macOS 13 or later, Ubuntu 20.04, Debian 11 or later, any other Linux with glibc 2.17 or later. dpkg --print-architecture or uname -m prints the word you need.

First run

Nothing here is code-signed, so the first launch takes one extra click. On Windows: More info, then Run anyway. On macOS: right-click kmap and choose Open; from macOS 15, System Settings, Privacy & Security, Open Anyway.

checksums.txt carries a SHA-256 for every file above.
