Description:
Abstract:
This data set presents the best available digital GIS (Geographic Information System) trailsystem map for the Ometepe Fieldschool fieldsite, Nicaragua, of the Maderas Rainforest Conservancy. It covers the foot of Maderas vulcanoe base near San Ramon. It is produced in ESRI ArcGIS 9.3 and data were collected in the field during a field school by students with an etrex Garmin GPS in decimal degrees, latitude longitude WGS84. This dataset has an accuracy of +- 10 meters and is available for furrher ground-truthing, extension and improvement. The dataset consists mainly of a line shapefile with an attribute table, but several waypoints were also collected. The data set can also be obtained as a jpg.
Purpose:
Create a publicly available digital trail map for field courses, students and other users of the Ometepe Field site of the Maderas Rainforest Conservancy, located at the foot of the Maderas vulcano near San Ramon, Nicaragua, Central America. This map is part of the digital infrastructure for this field site.

Lineage:
Methodology:
Methodology_Type: Field
Methodology_Description:
Data got collected in the field by walking trails and clicking waypoints and with the tracking function. We followed the existing trail system in Dec 2010 and January 2011. Data were downloaded into ArcGIS using the DNRGarmin software and the GarminGPS Mapsource for a check.

An existing hardcopy trailsystem map existed (credits author, and others, including Maderas Rainforest Conservancy) and was digitized and compared with the field data as needed.

Process_Step:
Process_Description:
Data got imported into ArcGIS 9.3 and cleaned for a consistent trail map, matching digitized trail maps from the Maderas Rainforest Conservancy and our own experience. The final product exist as shapefile and also as a jpg.
