Test Plan for Remote Sensing Information Subsystem Products Test Site 1 (Coastal)
This plan outlines the map products to be generated from Landsat imagery, airborne multispectral scanner imagery, and aerial photography of a test site on the Texas coast. The objectives of producing these maps are:
To determine the methodology necessary for developing each type of product.
To designate the size, scale, level of detail, and final format of each map within an initial phase of development of remote sensing products.
To designate specifications for the generation of equivalent products from aerial photography to be used in comparison evaluations.
The map products and data analysis procedures described here are based on:
Objectives outlined in the Applications System Verification and Transfer (ASVT) Project Plan (McCulloch and McKain, 1978).
State agency coastal information needs and listings of possible products developed in conjunction with the User Advisory Group.
The Remote Sensing Information Subsystem (RSIS) Level I Design and Design Review documents.
As such, the descriptions contained herein are primarily conceptual and are derived from only limited hands-on experience with Landsat imagery and digital image processing hardware and software. Present time schedules call for the software required for full analysis of data over the Coastal Test Site to be available in early 1981.Bureau of Economic Geolog

Annotated Bibliography of Techniques for Image Enhancement and Interpretation in Remote Sensing
The purpose of this annotated bibliography is to provide the user of the Remote Sensing Information Subsystem (RSIS) with brief descriptions of recent research techniques of image enhancement and their applications to specific image interpretation problems. Table 2 of the May 1979 ASVT/RSIS Technical Report entitled "Functional Design Narrative Descriptions" listed digital image processing requirements of the RSIS. The references in this bibliography were chosen because they describe these processing requirements. The format of that table was modified slightly and used as the outline for Section One of this bibliography.
The bibliography is not intended to be an exhaustive compilation of all pertinent articles. Such a collection would be outdated as soon as it was printed. It does, however, contain a broad sampling of the recent remote sensing literature. We tried not to include multiple references to the same technique, but some repetition was necessary in order to fully describe some procedures of image enhancement and interpretation.Bureau of Economic Geolog

Plan for Economic Evaluation of Products from the Remote Sensing Information Subsystem (RSIS)
The objective of this proposed analysis is to compare the cost and accuracy of map production using existing methods with map production using the Remote Sensing Information Subsystem (RSIS). Both methods require surface visits in order to control the validity of interpretations. Existing methods imply the use of aerial photography at appropriate scales with conventional photo interpretation techniques. Map units are delineated directly on the photograph, on an overlay, or a map base and, through the process of scribing and other cartographic techniques, a final map product is produced.
Use of the RSIS implies the use of Landsat or airborne multispectral scanner data in a digital processing system which will operate in an interactive manner with the interpreter, supplemented by aerial photography. A keyboard cathode ray tube (KCRT) will be the primary means for data display and for the interpreter to direct further data analysis. During the TNRIS/NASA Joint Project, hard-copy output from digital data is dependent upon the use of a Matrix Color Camera to produce Polaroid prints and film transparencies. The RSIS will accept hard-copy input (maps and aerial photographs) for use with overlay production but will not digitize photography.Bureau of Economic Geolog

Definition of Optimum Isocls Parameters for RSIS Interactive Data Anaylsis , Texas Coastal Applications Test Site
Data tapes for a specified window are processed through a program called ISOCLS (Iterative Self-Organizing Clustering). The user supplies several input parameters, including the spectral distance between clusters (DLMIN) and the maximum standard deviation for the values within a cluster (STDMAX). The purpose of this study was to vary these two parameters and analyze the differences in images produced from the same data.Bureau of Economic Geolog

Test Plan for Remote Sensing Information Subsystem Products Test Site 2 and 5 (High Plains and Trans-Pecos Texas)
This plan outlines the map products to be generated from Landsat imagery, airborne multispectral scanner imagery, and aerial photography of test sites in the High Plains of the Texas Panhandle and in Trans-Pecos Texas. The objectives of producing these maps are:
To determine the methodology necessary for developing each type of product.
To designate the size, scale, level of detail, and final format of each map within an initial phase of development of remote sensing products.
The map products and data analysis procedures described here are based on:
Objectives outlined in the Applications System Verification and Transfer (ASVT) Project Plan (McCulloch and McKain, 1978).
State agency information needs and listings of possible products developed in conjunction with the User Advisory Group.
The Remote Sensing Information Subsystem (RSIS) Level I Design and Design Review documents.
The descriptions contained herein are primarily conceptual and are derived from limited hands-on experience with Landsat imagery and digital image processing hardware and software. Analysis of the High Plains region will make maximum use of experience gained in the coastal test site using ISOCLS for unsupervised classification of land cover/land use. The image enhancement techniques to be used for geologic applications in the Trans-Pecos region have not previously been applied as part of RSIS.Bureau of Economic Geolog

Remote Sensing of the Coastal Applications Test Site Test 1: Economic and Accuracy Evaluation of Mapping Techniques
This evaluation of mapping techniques was prepared as part of the Texas Applications System Verification and Transfer (ASVT) project, which is a joint effort of the Texas Natural Resources Information System (TNRIS) Task Force and the National Aeronautics and Space Administration (NASA). The goal of the ASVT project, as described by McCulloch and McKain (1978), is to develop a Texas Natural Resources Inventory and Monitoring System (TNRIMS). The TNRIMS is designed "to assist agencies of the State of Texas in carrying out their statutory responsibilities in the areas of natural resources and the environment" (Finley and Baumgardner, 1981b, p. 2). This study evaluates the use of one component of the TNRIMS, the Remote Sensing Information Subsystem (RSIS), in its developmental state between March and August 1981.
The project study area is part of the Coastal Applications Test Site (CATS) (fig. 1), one of five test sites in Texas included in the ASVT project. All test sites were selected to sample the wide variety of land cover/land use categories in the state. The coastal test site was chosen for this evaluation of the RSIS according to (1) state agency needs for information on coastal wetlands, (2) availability of personnel with experience in mapping coastal areas, (3) access to supplementary land cover/land use data, and (4) diversity of land cover/land use types in the area.Bureau of Economic Geolog

Initial Report on the Geology of the Northeastern Part of the New Braunfels, Texas
This brief report describes initial progress on geologic mapping and paleontologic studies that are being conducted in the vicinity of New Braunfels, Texas. The primary objective of this work is to produce an accurate geologic map that will be printed on the new 1:100,000-scale map of the New Braunfels, Texas, 30 X 60 minute quadrangle, which is in preparation by the U.S. Geological Survey. A planimetric version has been printed, but the final topographic map is not yet available. Our initial mapping has been completed on 1:24,000-scale topographic maps and is intended for compilation at 1:100,000-scale. Partial funding for the second year of the study has been approved. Work during year two will continue the mapping into quadrangles adjacent to those mapped in year one. Paleontologic work by Dr. Will Elder will continue as part of the in-kind contribution by the U.S. Geological Survey to this effort. Dr. E. G. Wermund has described this project to several groups for whom the geology of this area is of interest. Draft copies of the mapping accomplished to date have been given to the Edwards Underground Water District, potentially for entry by them into a GIS, and copies will be made available to other interested parties as requested. In addition, the South Texas Geological Society has passed a resolution commending this initiative, supporting this new mapping effort, and offering the help of their membership.Bureau of Economic Geolog
