Sanborn has great experience digitizing planimetric mapping data from aerial photography for use as a base layer of a GIS. With speed and consistency intrinsic to our data processing, Sanborn produces accurate and aesthetically pleasing planimetric data that can meet the specifications of any GIS. Standards and specifications are essential to facilitate the development and sharing of geospatial data and products. National Geospatial Program (NGP) standards and specifications define requirements to ensure that all maps and data prepared by NGP, in support of The National Map, are consistent in accuracy, structure, format, style, and content. LIST OF VOLUMES OF TOPOGRAPHIC INSTRUCTIONS BOOK 3. MAPPING PROCEDURES STANDARDS FOR THE TREATMENT OF MAP FEATURES Instructions for selecting, classifying, and symbolizing the principal features shown on topographic maps. Part 3A. Chapters 3AA9. AERIAL PHOTOGRAPHY FOR MAPPING. Towill performs more than aerial photogrammetric mapping projects each year, ranging from large-scale ( or ) mapping used for engineering design projects to small-scale mapping (, or ,) for planning, facilities management, and environmental restoration projects. High-quality aerial photography is the foundation for most photogrammetric maps, which produce the.

CDOT contracts out all aerial surveys as the aerial photography and mapping equipment is not available in the department. As such CDOT relies upon the expertise and experience of the aerial mapping consultant to provide guidance and products that will meet the needs of the project. The survey fieldwork is most.   Services Required: Digital Orthophoto, Color Aerial Photography, LiDAR, 1 Foot Contours, Planimetric Updates, and Impervious Surfaces. The City intends to utilize one consultant to complete all phases of the project. The City reserves the right to reject any or all submittals. II. GENERAL INSTRUCTIONS A. SPECIFICATIONS FOR SURVEYING, AERIAL PHOTOGRAPHY AND MAPPING. OF A PROPOSED TRANSMISSION LINE CORRIDOR. Introduction.

imagery is used to create engineering grade mapping and terrain files for planning and design activities. 2. Photograph Collection a. Aircraft The Department’s aircraft used to flying aerial photo missions is a Cessna Caravan It has an approximate maximum flying altitude of 25, ft. and a maximum air speed of knots ( mph). Planimetrics is the study of plane measurements, including angles, distances, and areas.. History. To measure planimetrics a planimeter is used. This rather advanced analog technology is being taken over by simple image measurement software tools like, ImageJ, Adobe Acrobat, Google Earth Pro, Gimp, Photoshop and KLONK Image Measurement which can help do this kind of work from digitalized images. AERIAL PHOTOGRAPHY, TOPOGRAPHIC AND/OR PLANIMETRIC MAPPING AND RELATED WORK ALL SUPERVISORIAL DISTRICTS 3 VOTES IT IS RECOMMENDED THAT YOUR BOARD: 1. Find that the contract work is exempt from the provisions of the California Environmental Quality Act (CEQA). 2. Award contracts for "Aerial Photography, Topographic and/or Planimetric.   Data Acquisition. Successful aerial data acquisition is the foundation of any mapping program. Missteps in collecting aerial data can increase a program’s cost due to re-collection efforts, production delays and issues that may cause the data produced to fall outside required specifications.
