Description: | Technical report Abstract: An experimental map showing winter conditions in an arctic area was developed by modifying an existing orthopictomap. Modifications included the addition of vegetation and hydrologic information which are considered feasible to be derived from thermal infrared imagery obtained in winter. As suitable infrared imagery of the study area was not available, the information was derived from summer aerial photography. Interpretation of the photography was based on results obtained from thermal infrared research in other arctic areas. The mapped area covers a 7 1/2 minute quadrangle at a scale of 1:25,000 in the Fort Greely, Alaska, area. The processes that cause changing surface temperatures are discussed. Examples of thermal infrared imagery (8-14 micrometers) are presented that illustrate some of these energy transfer processes, as well as some of the types of features included on the experimental map. Recommendations for a production map format include a climate summary suitable for preliminary flight planning for the acquisition of thermal imagery; this is printed on the back of the map. Uses suggested for this type of map are 1. Land navigation assistance on the basis of vegetation characteristics and Boundaries 2. Camouflage and concealment characteristics of vegetated areas 3. Cross-country movement planning on the basis of an initial assessment of the probable condition of lakes and streams that may have to be crossed or avoided 4. Location of water supplies 5. Guidance in planning for and utilizing new thermal infrared imagery. |
