ASPRS INTERIM ACCURACY STANDARDS FOR LARGE-SCALE MAPS The American Society for Photogrammetry and Remote Sensing - 1988 These standards have been developed by the Specifications and Standards Committee of the American Society for Photo- grammetry and Remote Sensing (ASPRS). The contractor shall submit a written request Contract service work 13 City of Minneapolis C. County parcel database 15 Washington County D. Street centerline data set to which These standards were a response to the need for scale-independent accuracy standards. A compressed mosaic is also provided in SID/SWD format (3:1). "ASPRS Accuracy Standards for Large-Scale Maps" (1990) and the "ASPRS Guidelines, Vertical Accuracy Reporting for LiDAR Data" (2004). A major feature of these ASPRS standards is that they indicate accuracy at ground scale. A summary: Nope I started reading it and just stopped. . These standards were updated through-out the 1940's but remained unchanged until the 1990's when the American Society for Photogrammetry and Remote Sensing (ASPRS) published the ASPRS Accuracy Standards for Large-Scale Maps. Photogrammetry and Remote Sensing (ASPRS) (cf., Accuracy Standards for Large-Scale Maps). What are common topological errors with line features? Conclusion.

Perkins said, "we have important work ahead as we work to complete new ASPRS Accuracy Standards for Digital Geospatial Data, to replace the existing ASPRS Accuracy Standards for Large-Scale Maps, 1990, and the ASPRS Guidelines, Vertical Accuracy Reporting for Lidar Data, 2004." The most commonly used data standard for county and municipal mapping applications are the American Society of Photogrammetry and Remote Sensing (ASPRS) Class I and II. Accuracy standards vary in complexity and usability. 4. accuracy standards for maps and related geospatial products 5. photogrammetric mapping standards and specifications 6. cadastral or real property survey accuracy standards 7. hydrographic surveying accuracy standards 8. structural deformation survey standards 9. geodetic control survey standards 10. state and local accuracy standards 11. The contractors three (3)-inch imagery shall meet accuracy specifications for 1=25 mapping with a RMSE of 0.5 feet using ASPRS Accuracy Standard for Large Scale Maps, Class 1 Map Accuracy. 2. It can be These standards establish the map accuracy by establishing the difference between the location of a feature in a spatial data set and its true position on the earth. Intended to be finalized in 2014, the new standards include accuracy thresholds for digital orthophotos and digital elevation data, independent of published map 4 7 16. proposed. It is anticipated that It is rare for a7.5-minute map to fail the test, but thishappens on occasion. The vertical control supported the production of 1=100 digital orthophotos and the generation of 2 contours. no. SECTION 2 Base Map Metadata. For example, using the new standard, a Scope of work, could specify that digital orthoimagery, digital planimetric data, or scaled maps must be produced to meet ASPRS Accuracy Standards for 7.5 cm RMSEx and RMSE y Horizontal Accuracy Class. Accuracy Standards for Large Scale Maps (ASLSM) of the American Society for Photogrammetry and Remote Sensing is analyzed according to the sample size, as well as the relation between the limiting errors (thresholds), stated by the standard as a root mean squared error, and the actual root mean squared error of the product. DOT Map Standards 10 2-8. Standards for Large Scale Maps (ASPRS 1990) classification standard. ASPRS Accuracy Standards for Large- Scale Maps evaluates positional accuracy for the x-component and the y-component individually. This quickly became accepted as the de facto standard for the industry. This standard supersedes and replaces prior ASPRS accuracy standards including the ASPRS Accuracy Standards for Large Scale Maps (1990) [PB1] and ASPRS Vertical Accuracy Reporting for Lidar Data (2004).

But just what is a 100-scale digital ortho? The data was flown on April 13th, 14th, 18th and 23rd of 2015 using an UltraCam Eagle camera and complies with the American Society for Photogrammetry and Remote Sensing Accuracy Standards (ASPRS) for Class 1, large scale maps at 1" = 1038- These accuracy standards for large-scale maps (generally 1"=1000' and larger {i.e. All spatial data generated shall conform to SDSFIE 3.0. Another map accuracy standard of potential interest, but not discussed in this publication, is the American Society for Photogrammetry and Remote Sensing (ASPRS) Accuracy Standards for Large-Scale Maps. ASPRS LIDAR GUIDELINES: Horizontal Accuracy Reporting THE CONTENTS. It was developed to serve as a common standard that can be used by state, regional and local governing bodies in Virginia to meet their needs for a map accuracy standard. ASPRS published a supplement to these guidelines in the July 1989 PE&RS entitled, "ASPRS Interim Accuracy Standards for Large-Scale Maps." In 1958, the USGS began systematicallytesting the accuracy of its maps.Presently, accuracy testing is performedon 10 percent of the mapping projects ateach contour interval as a method ofcontrolling overall quality.

ASPRS INTERIM ACCURACY STANDARDS FOR LARGE-SCALE MAPS These standards have been developed by the Specifications and Standards Committee of the American Society for Photogrammetry and Remote Sensing (ASPRS). The existing standard is primarily intended for published maps and has several shortcomings when applied to new digital technologies. sheet. Based upon a special symposium sponsored by the U.S. Environmental Protection Agency (EPA), Remote Sensing and GIS Accuracy Assessment evaluates the important scientific elements related to the performance of accuracy assessments for remotely sensed data, Thus, digital spatial data of known ground-scale accuracy can be related to the appropriate map scale for graphic presentation at a recognized standard.
