Data
organization. All CAPS results and many intermediate
results are available for download. This
section provides links to the various versions of IEI, the CAPS landcover,
results of individual metrics, and settings variables. Data are available in grouped .zip files,
listed below. In addition, individual
metrics and settings variables are available in separate .zip files.
Data
formats.
With this release, we’re supplying all grids as geoTIFFs
as well as ESRI Arc grids. GeoTIFFs have several advantages over Arc grids: they are
typically more space-efficient, they can be viewed in most image viewers and
browsers as well as with GIS software, they can contain display formats
intrinsically rather than requiring a separate application-specific legend, and
most importantly, geoTIFF is a public domain format,
as opposed to ESRI’s proprietary format.
As open-source GIS software (such as QGIS) becomes more sophisticated
and stable, we anticipate many users will migrate to open source GIS. To support this migration, we plan to make
our data available in public domain formats such as geoTIFF.
Scaling. Scaled metrics and IEI
are scaled from 0-1; in geoTIFFs, these grids are
expressed in terms of percent (scaled 0-100).
Raw metrics and settings grids are scaled in original units, unique to
each grid; in geoTIFFs, these grids are scaled from
0-255. The CAPS final landcover, capsland, represents landcover classes using integer
classes (see Appendix H). GeoTIFF versions are already colored appropriately; legends
files for QGIS, ArcView 3.3, and ArcMap are supplied
for the Arc grid.
The
coordinate reference system for all data is Massachusetts mainland State Plane,
NAD83.
Basic results
These are the most basic results, for those who want immediate
gratification. This .zip file consists
of two files in geoTIFF format:
iei_i CAPS
Integrated IEI (scaled 1-100)
capsland CAPS landcover grid

Standard
results
These results contain all four versions of the IEI, as well as
landcover. In Arc grids, IEIs are scaled
0-1; In geoTIFFs, they are scaled 0-100.

Five color
integrated IEI
The grid used to produce the IEI town maps (“areas of potential
high ecological integrity”) are available in a geoTIFF. This grid is the top 50% integrated IEI,
displayed in five color gradients (green for forests, orange for shrublands, yellow-brown for coastal uplands, blue for
freshwater wetland & aquatic, and cyan for coastal wetland aquatic). The values in this grid encode the color;
they are not meaningful otherwise.

DEP important
habitat
The DEP Massachusetts
Habitat of Potential Regional and Statewide Importance data are available in a geoTIFF. This grid
is simply the top 40% of integrated IEI (iei_i >
0.6); cells with a value of 1 are within DEP important habitat.

Raw metrics
These .zip files contain all raw metrics results. See Appendix C for a list of metrics, grid
names, and brief descriptions, and Appendix F for the contribution of each
metric to each community’s IEI. Raw
metrics are scaled in original units, unique to each metric; geoTIFF versions are rescaled from 0-255. Integrity increases with decreasing values of
stressor metrics, and increasing values of resiliency metrics.

Arc grids: http://jamba.provost.ads.umass.edu/web/caps2011/arczips/metricsraw.zip (760 MB)
Scaled
metrics
These .zip files contain all scaled metrics results—these are the
raw metrics rescaled by percentiles within each community. See Appendix C for a list of metrics, grid
names, and brief descriptions, and Appendix F for the contribution of each
metric to each community’s IEI. Scaled
metrics range from 0 to 1 (higher values correspond to higher integrity for all
metrics); geoTIFF versions are scaled by percent
(0-100).

Arc grids: http://jamba.provost.ads.umass.edu/web/caps2011/arczips/metricsscaled.zip (169 MB)
Settings variables
These .zip files contain mixed (unscaled) settings variables. See Appendix D for a list and brief
description of settings variables, and Appendix G for grid names and
weights. Settings variables are scaled
in original units, unique to each variable; geoTIFF
versions are rescaled from 0-255.

Arc grids: http://jamba.provost.ads.umass.edu/web/caps2011/arczips/settings.zip (477 MB)
Individual grids
Metrics (both raw and scaled) and settings variables are also
supplied as individual GeoTIFFs. These data are the same as those listed
above; we’re supplying grids individually for the convenience of those who just
want results for a metric or two.
Individual grids range in size from <1 to 18 MB.

Additional
data
A
large collection of additional GIS data for Massachusetts are available from
MassGIS (http://www.mass.gov/mgis/massgis.htm). Many of these data
layers, such as town boundaries, ecoregions, watersheds, aerial photos, and
USGS topographic maps are extremely helpful for viewing and interpreting CAPS
results.
Running
CAPS for Massachusetts requires a large number of additional intermediate data
sources not linked above. These data are
available on request.
