1». THE CRIES - GEOGRAPHIC INFORMATION SYSTEM 
(GIS) 
This section describes the Geographic 
Information System (GIS) component of the 
Comprehensive Resource Inventory and 
Evaluation System (CRIES) - Resource 
Information System (RIS) as modified for IBM, 
Model AT micro-computers using the MS-DOS 
operating system. The CRIES-GIS provides the 
capability to store, edit and process digital 
map data and creates the master data base 
(disk files) for subsequent analysis. The 
various phases are used to input, retrieve, 
combine, statistically analyze, overlay, 
modify and display the results in the 
form of various statistical summaries or 
computer maps. Typical products include area 
measurements and displays of single map 
attributes or combinations at various map 
scales. 
The IBM-AT (or compatible MS-DOS micros) 
Version 6.0 requires only 256K of RAM, is 
menu-driven, supports a data base of 65,535 
rows by 65,535 columns (the individual 
information cells), multiple attributes 
(information layers) with attribute values 
(or classes) of 1 to 65,535, depending on the 
user-selected bit field. The system requires 
the 80286 processor and uses the 80287 co 
processor to accelerate mathematical 
operations where available. However, a 8088 
(with optional 8087) (IBM -XT) processor 
may be used if lower processing speeds are 
acceptable. The digitizing is supported using 
the TECMAR color graphics master board. The 
software minimizes data storage requirements 
through the use of, user-se1ectab1e, bit- 
fields based on the complexity of map 
attributes. (1, 2, 3, 4, 5, 8 or 16 bit 
fields). The bit size selected (2 to the n.th 
power - 1, in which n = bit size) determines 
the number of attribute values per attribute. 
For instance, for n = 8, 256-1 attributes 
values may be represented (for n = 16 , 65536 
-1). A standard, 80 or 132-column printer is 
required to generate the output for selected 
phases and computer printer maps. The more 
attractive maps generated by the Choroline 
phase require an EPSON, 80 or 132 column, or 
compatible, dot matrix printer. User- 
Overview of CRIES- GIS Modules, Phase and 
Sub-phases. 
An short descriptive overview of the CRIES- 
GIS, which comprises 7 major modules, 30 
phases and 8 sub-phases, is provided, below: 
The CRIES-GIS-INPUT module, used for primary 
data manual or electronic data entry, 
verification and editing, consists of 4 
phases and 2 sub-phases : 
1. EDITCELL - permits geocoding and editing 
of a raster file 
2. DIGITIZE - converts analog map data Into 
digital form using an X-Y digitizing tablet 
2.1 MONODIG - this sub-phase permits low 
resolution, monochrome digitizing 
2.2 COLORDIG - this sub-phase permits 
high resolution, color digitizing 
3. POLYFILL - converts converts polygon data 
created by DIGITIZE into a raster file 
4. CUTTER - uses existing raster files to cut 
outline boundaries into overlapping raster 
files 
The CRIES-GIS-STATISTICS module, used to 
provide statistical summaries of raster 
files, consists of 3 phases : 
1. HISTGRAM - provides a frequency table and 
a histogram from a single raster file 
2. TALLY - calculates summary statistics for 
a user-specified rectangular subwindow of a 
single or multiple raster files 
3. CROSSTAB - creates a crosstabu 1 ation of 
two or more raster files of up to 255 
attribute values 
The CRIES-GIS-ANALYSIS module, used to 
analyze raster files, consists of 7 phases : 
1. EROSION - calculates erosion rates using 
the Universal Soil Loss Equation using user- 
specified variable weights 
2. GROUP - groups ranges of attribute values 
into user-selected single values using single 
or multiple raster files 
3. INVERT - inverts the range of attribute 
values in a raster file 
4. MATCH - creates new attribute values for 
user-specified co-occurrences of existing 
attribute values of multiple files 
5. N0RMALIZ - normalizes the range of 
attribute values based on user-defined limits 
6. OVERLAY - permits weighted and unweighted 
overlay analysis of attribute values of 
corresponding grid cells with optional 
overriding values 
7. SEARCH - permits proximity analysis from 
points, lines and areas 
The CRIES-GIS-TERRAIN module, used to support 
three-dimensional terrain analysis, consists 
of 2 phases: 
1. SURFCELL - creates a trend surface in the 
form of a raster file using X, Y, Z point 
data as input 
2. SURFAREA - (under development) creates a 
trend surface in the form of a raster file 
using area data as input. This phase permits 
via the use of sub phases calculation of 
slope gradient, slope length and orientation. 
The CRIES-GIS-DISPLAY module,used to display 
the contents of raster files in the form of 
character maps or digital form, consists of 
three phases:
