Geodatabases

Currently, reverse geocoding for each country is done using the GeoNames database.
Slovakian database is an exception, as it contains data both from GeoNames (cca 7000 entries) merged with hiking.sk POIs (cca 2000 entries, obtained with kind agreement of Ľubo).

GeoNames contains mostly municipalities and lacks touristic points. If you can provide larger database of touristic POIs anywhere in the world, please contact me.

Notes on gpx log processing

Inserted gpx log consists of series of points, its content can be following (two points of a track are displayed here):

Each point has a latitude, longitude, (optional) elevation, date, time and other attributes. AnalyzeMyTrack! treats whole log file as a single track, ingoring multiple track segments or waypoints. Elevation is an optional attribute of a track point – in case of missing elevation, "real distance" between two points is computed in the same way as "flat distance", using the haversine formula.

How reverse geocoding works?

Geodatabase consists of thousands data points with text labels. Each entry represents a geographical place with latitude, longitude and name. Thus, each minucipality, disregarding its real size, is represented only as a sigle point.

Your track is represented as a series of points. Fitting the points from your track to geographical entries in the geodatabase is done in following way:

Precision parameter determines size of the circular window around a point when searching for named geopoints.

Understand the data table

Analysis provided by AnalyzeMyTrack! includes a table which may look like following:

Data entries (rows) in the table have following meaning:

• at the beginning of the track (0.0km) no annotation was found in the database (— sign)
• 5.61km later, place annotated as "Vrakuna" was close enough to your track (closer than selected precision) and was associated with this part of track
• relevance of "Vrakuna" is 44% (*)
• few hundreds metres later (6.07km from beginning of the track), you left "Vrakuna" and entered un-annotated part of track
• etc.

Note that one entry in the table usually merges more points of your track.

The country list is quite long, contains 242 countries, thus selecting desired country can be a pain. AnalyzeMyTrack! employs hostip.info database and predefines a country in the list according to your IP address. However, IP tracking is not accurate and, additionally, your gpx log can be located in different country than your current location.

Due to this reasons, you can force country selection is the list via following URL:
http://my-track.net/?country=name

For example, if you want United States of America to be predefined in the country list, the URL is:
http://my-track.net/?country=United_States_of_America

Note that the country name must be written as is in the country list (case-sensitive) and spaces must be replaced by underscore characters.

• if you insert URL of the file make sure the address begins with http://
• inserted file must be in gpx format
• gpx log should contains at least one trackpoint (trkpt tag)
• the trackpoints must be associated with date and time stamps (time tag) – missing date and time occurs when gps log is converted via OziExplorer. Try GpsBabel converter instead, works better.
