LBA-ECO LC-01 Hydrography, Morphology, Edaphology Maps, Northern Ecuadorian Amazon
Get Data

Revision date: January 26, 2012

Summary:

This data set provides map images of hydrographic, morphologic, and edaphic features for the northern Amazon Basin in eastern Ecuador. The hydrographic data are available at two scales based on the 1:50,000 and 1:250,000-scale topographic source maps that were generated in 1990 and 1993, respectively. Morphological and edaphological data were digitized from a 1:500,000 map published in 1983. There are 3 compressed (*.zip) data files with this data set.

Implementation of the LBA Data and Publication Policy by Data Users:

The LBA Data and Publication Policy [http://daac.ornl.gov/LBA/lba_data_policy.html] is in effect for a period of five (5) years from the date of archiving and should be followed by data users who have obtained LBA data sets from the ORNL DAAC. Users who download LBA data in the five years after data have been archived must contact the investigators who collected the data, per provisions 6 and 7 in the Policy.

This data set was archived in January of 2012. Users who download the data between January 2012 and December 2016 must comply with the LBA Data and Publication Policy.

Data users should use the investigator contact information in this document to communicate with the data provider. Alternatively, the LBA Web Site [http://lba.inpa.gov.br/lba/] in Brazil will have current contact information.

Data users should use the Data Set Citation and other applicable references provided in this document to acknowledge use of the data.

2. Data Characteristics:

There are three data files in this data set provided as compressed *.zip files. These are zipped ESRI ArcGIS shapefiles. When unzipped, each shapefile contains seven files (.dbf, .prj, .sbn, .sbx, .shp, .shp.xml, .shx.). Each shapefile contains polygon geometry with the following projection parameters:

hy_oriente.zip: morphologic and edaphologic features

Hydrographic 1:50,000 scale

hy_oriente_polygon.xxx: where file extension is .dbf, .prj, .sbn, .sbx, .shp, .shp, .xml, or .shx; hydrographic coverage at the 1:50,000 Scale.

Attributes

hy_profors.zip: hydrographic features

Hydrographic 1:250,000 scale:

hy_profors_polygon.xxx: where file extension is .dbf, .prj, .sbn, .sbx, .shp, .shp, .xml, or .shx; hydrographic coverage at the 1:250,000 scale.

Attributes

morfo.zip: morphologic and edaphologic features

Morphology

morfo_polygon.xxx: where file extension is .dbf, .prj, .sbn, .sbx, .shp, .shp, .xml, or .shx; morphologic and edaphologic features.

3. Data Application and Derivation:

This data set may be used to gain greater understanding of the northern Ecuadorian Amazon or to inform other analyses (e.g., examining areas of richer soils for differences in LULC and LULC changes) and for cartographic representation in larger-scale maps of the hydrographic network in the Oriente.

Derivation techniques:

All data were digitized from a variety of paper maps. Morphological and edaphological data were digitized from 1:500,000 paper map. Attribution occurred during digitization. 1:50,000-scale topographic maps were digitized.

The hydrographic features on the 1:250,000-scale PROFORS map were digitized. An RMSE of less than 0.01 was achieved in the digitization.

Site description

The northern Ecuadorian Amazon is significant from social, biophysical, and geographical bases, with complex terrain and land-use variability. Settlers in the Napo and Sucumbios provinces, the two dominant Cantons or States, settled on 50 ha plots, clearing primary forest to grow subsistence crops, coffee, and for pasturage. The western Amazon region, bordering the Andes and lying at the headwaters of the Amazon River basin, possesses several major centers of endemism, including the Napo. Despite the regions global biodiversity and carbon sequestration significance, agricultural settlement and concurrent deforestation threaten the region. A comprehensive description of the Oriente can be found in Messina and Walsh (2001).
