rmkmapper

Rationale

The Estonian State Forest Management Centre maintains many recreational sites (or points of interest in rmkmapper's terms). There are two issues:

• Despite much fanfare about launching an open data initiative years ago, this has fizzled in Estonia and as such, most public sector organizations including the SFMC has not provided machine-readable data of their activities
• The official site has no overview map of all the various types of sites

rmkmapper solves these issues by:

• providing a command-line tool to crawl SFMC's web site and compile a machine-readable (GeoJSON) dump of all the POIs
• providing a simple web application displaying a zoomable, filterable, interactive map of all the POIs

An occasionally updated demo is available.

In addition, this project allows converting GPS tracks to GeoJSON from various formats (using GPSBabel for the heavy lifting) and provides a Perl module for conversion between the L-EST 97 and WSG84 (latitude / longitude) coordinate systems.

Command-line tool

The CLI tool requires a reasonably recent version of Perl 5, HTML::TreeBuilder, JSON::XS, LWP::Simple.

Usage:

rmkmapper.pl [-p | -t url] [-o dir] [...]

Print a JSON string representing all RMK objects.

--ofile-dir, -d   - Directory containing pre-downloaded RMK object HTML files.
                    Skip crawling for object files on the web. Note that this
                    mode is more tolerant to errors, merely warning if a file
                    cannot be parsed into an object. Use a command similar to
                    the following to generate a local cache of object files in
                    cwd:

                    wget -O - http://eid.ee/3te | 
                    wget -rLEnH -A '*.html' -l0 -Fi - -B http://loodusegakoos.ee
--pois, -p        - Generate a GeoJSON index of points of interest (default)
--tracks, -t      - Generate a GeoJSON index of tracks based on the passed GPS
                    file or URL (requires gpsbabel on $PATH). Can be passed
                    several times for a combined dump.
--tracks-type, -T - The type of the tracks file, passed to gpsbabel via -i
--max-num, -n     - Maximum number of POIs to parse, for debugging
--ugly, -u        - Print compact JSON with minimal whitespace
