 with the ultimate goal of importing it into
 <a href="https://www.openstreetmap.org">OpenStreetMap</a>. It
 is oriented towards processing non OSM external datasets.</p>
+<p>This project uses a huge amount of data (and disk space) if you start
+from the original nation wide datasets, which are too large to
+edit. There is a contrib script in the git sources I use to start
+breaking down the huge files into managable pieces.</p>
+<p>The goal of this project is two-fold. One is to support field data
+collection using OpenDataKit. The
+<a href="https://hotosm.github.io/osm-fieldwork/">osm-fieldwork</a> project can
+be used to convert the ODK data files into GeoJson and OSM XML. This
+project then supports conflating that field collected data with
+current OpenStreetMap. Otherwise this is a time-consuming process to
+do manually.</p>
+<p>The other goal is focused on emergency access in remote areas. This is
+improving the Motor Vehicle Use Map (MVUM) datasets of all highways
+(mostly jeep trails) in OpenStreetMap.  The current data in OSM was
+often imported complete with bugs in the original dataset, or the only
+details are <em>highway=track</em>. All of these have a US forest service
+reference number and name. Adding those makes it much easier to
+communicate a location.</p>

-<p>This looks for duplicate buildings both in the
-external dataset, and in OSM. This has been used with
-multiple datasets, namely the Microsoft ML Building
-footprints, Overture, and others.</p>

-<p>This looks to find a building when the data is only a POI. Many
-external datasets are a list of buildings, like schools or
-hospitals. In OSM the only metadata for the feature may be
-<em>building=yes</em>. Also field collected data with ODK Collect is also a
-POI, and we want the data that was collected to be merged with any
-existing OSM features.</p>

+<p>This program doesn't require a database, unlike the other conflation
+programs. It is focused on <a href="odkconflation/">conflation OpenDataKit</a>
+with OpenStreetMap, as well as conflating <a href="highways/">rural
+highways</a>. It'll conflate any two datasets in either GeoJson
+or OSM XML format. While this is currently under heavy development and
+debugging by processing large amounts of data to track down all the
+obscure bugs in the original datasets, or the conflation process.</p>
+<h3 id="the-data">The Data<a class="headerlink" href="#the-data" title="Permanent link">&para;</a></h3>
+<p>Much of the process of conflation is splitting huge datasets into
+managable sized files. Since that process is <a href="https://github.com/hotosm/osm-merge/tree/main/contrib">mostly
+automated</a>, I
+have a collection of files where I have done that part. Since
+conflation also requires converting the original datasets, the
+original files are included, the converted files to OSM XML &amp; GeoJson,
+and the results of conflation. Not all the national forests and parks
+have been conflated yet, but the data is there for others that may
+wish to try. The <a href="https://www.senecass.com/projects/Mapping/SourceData/States/">Map
+Data</a> is
+on a slow server, sorry. Disk space is cheaper than network bandwidth.</p>
