Overview
Since August 2002, we have been actively working toward a Geographic
Information System (GIS) for the Los Amigos Conservation Area. Our
objectives have been to:
- collect and organize available geographic
data
- to show possible use of the system in education, training
and research; and
- present research results through print and
digital means of publication.
A geographic metadatabase has been compiled from various sources,
including important files for the Los Amigos Conservation Area
provided by colleagues at the Amazon Conservation Association, and
files for Madre de Dios, Peru, and the American tropics that have been
opportunistically collected during the last year. We continue to
gather and input general basemaps, satellite images, climatic data,
human population data, and more. In October 2002 we added 15-meter
resolution Aster imagery and the first author used them to generate a
Digital Elevation Model of the Los Amigos Conservation Area (see DEM
imagery at left). A 2000 Landsat TM image was then overlaid on the
digital elevation model to create a 3D view of the area (see images at
left). We also just received our first IKONOS image from Satellite
Imaging Inc. (www.spaceimaging.com), which we will use to produce a
high-resolution vegetation map of the area.
Due to the scale of data available for the region, the Los Amigos GIS
has quickly expanded to encompass the entire geopolitical region of
the Department of Madre de Dios, Peru, and vicinity. This GIS system
is currently being used to support studies of the biodiversity in the
Los Amigos Conservation Area, but will soon be used for a broadened
analysis of the diversity, distribution, collection patterns, and
conservation of the plant diversity of Madre de Dios.
Currently, all GIS to Internet presentation is driven by the software
HTML Image Mapper offered by Alta 4 (www.alta4.com). Plans for the
immediate future are to convert the entire interactive system over to
ArcIMS, an internet map server technology by ESRI, while we will
continue to use Alta 4 for smaller scale presentations of specific
geospatial patterns.
