The survey date (ground condition) of the original paper map is 1886, the edition date is March, 1893 and this map was reprinted in 1929. A digital raster graphic (DRG) is a scanned image of a U.S. Geological Survey (USGS) standard series topographic map, including all map collar information. The image inside the map neatline is geo-referenced to the surface of the earth and fit to the Universal Transverse Mercator projection. The horizontal positional accuracy and datum of the DRG matches the accuracy and datum of the source map. The names of quadrangles which border this one appear on the map collar in their respective positions (N,S,E,W) in relation to this map."}}]},{"typeName":"topicClassification","multiple":true,"typeClass":"compound","value":[{"topicClassValue":{"typeName":"topicClassValue","multiple":false,"typeClass":"primitive","value":"imageryBaseMapsEarthCover"},"topicClassVocab":{"typeName":"topicClassVocab","multiple":false,"typeClass":"primitive","value":"ISO 19115 Topic Category"}},{"topicClassValue":{"typeName":"topicClassValue","multiple":false,"typeClass":"primitive","value":"Maps, Topographic"},"topicClassVocab":{"typeName":"topicClassVocab","multiple":false,"typeClass":"primitive","value":"LCSH"}},{"topicClassValue":{"typeName":"topicClassValue","multiple":false,"typeClass":"primitive","value":"Geological Survey (U.S.)"},"topicClassVocab":{"typeName":"topicClassVocab","multiple":false,"typeClass":"primitive","value":"LCSH"}},{"topicClassValue":{"typeName":"topicClassValue","multiple":false,"typeClass":"primitive","value":"Land Use"},"topicClassVocab":{"typeName":"topicClassVocab","multiple":false,"typeClass":"primitive","value":"LCSH"}},{"topicClassValue":{"typeName":"topicClassValue","multiple":false,"typeClass":"primitive","value":"Infrastructure"},"topicClassVocab":{"typeName":"topicClassVocab","multiple":false,"typeClass":"primitive","value":"LCSH"}},{"topicClassValue":{"typeName":"topicClassValue","multiple":false,"typeClass":"primitive","value":"Human settlements"},"topicClassVocab":{"typeName":"topicClassVocab","multiple":false,"typeClass":"primitive","value":"LCSH"}},{"topicClassValue":{"typeName":"topicClassValue","multiple":false,"typeClass":"primitive","value":"Bodies of water"},"topicClassVocab":{"typeName":"topicClassVocab","multiple":false,"typeClass":"primitive","value":"LCSH"}},{"topicClassValue":{"typeName":"topicClassValue","multiple":false,"typeClass":"primitive","value":"Landforms"},"topicClassVocab":{"typeName":"topicClassVocab","multiple":false,"typeClass":"primitive","value":"LCSH"}}]},{"typeName":"producer","multiple":true,"typeClass":"compound","value":[{"producerName":{"typeName":"producerName","multiple":false,"typeClass":"primitive","value":"Harvard Map Collection, Harvard College Library"}},{"producerName":{"typeName":"producerName","multiple":false,"typeClass":"primitive","value":"Harvard Map Collection, Harvard College Library"}}]},{"typeName":"productionDate","multiple":false,"typeClass":"primitive","value":"N/A"},{"typeName":"distributor","multiple":true,"typeClass":"compound","value":[{"distributorName":{"typeName":"distributorName","multiple":false,"typeClass":"primitive","value":"Harvard Geospatial Library"}}]},{"typeName":"timePeriodCovered","multiple":true,"typeClass":"compound","value":[{"timePeriodCoveredStart":{"typeName":"timePeriodCoveredStart","multiple":false,"typeClass":"primitive","value":"1886"}}]},{"typeName":"kindOfData","multiple":true,"typeClass":"primitive","value":["raster digital data"]}]},"geospatial":{"displayName":"Geospatial Metadata","name":"geospatial","fields":[{"typeName":"geographicCoverage","multiple":true,"typeClass":"compound","value":[{"otherGeographicCoverage":{"typeName":"otherGeographicCoverage","multiple":false,"typeClass":"primitive","value":"Massachusetts"}}]},{"typeName":"geographicBoundingBox","multiple":true,"typeClass":"compound","value":[{"westLongitude":{"typeName":"westLongitude","multiple":false,"typeClass":"primitive","value":"-71.560219"},"eastLongitude":{"typeName":"eastLongitude","multiple":false,"typeClass":"primitive","value":"-71.190116"},"northLatitude":{"typeName":"northLatitude","multiple":false,"typeClass":"primitive","value":"42.533374"},"southLatitude":{"typeName":"southLatitude","multiple":false,"typeClass":"primitive","value":"42.212769"}}]}]},"socialscience":{"displayName":"Social Science and Humanities Metadata","name":"socialscience","fields":[{"typeName":"samplingProcedure","multiple":false,"typeClass":"primitive","value":"The digital image was georeferenced to the true ground coordinates of the latitude and longitude corner tic marks of each quadrangle. A shape file was created containing control points at the latitude longitude coordinates of the tics. Those points were then projected to UTM, Zone 18, meters, NAD 27 which provided a consistent, standardized coordinate system to use across the entire collection of USGS quadrangles of Massachusetts. ArcMap 8.3 software was utilized to georeference the image to the projected control points, and a .tfw (world file) was generated and saved in association with the scanned image. The horizontal positional accuracy of a DRG is approximately the same as the accuracy of the published source map. However, there may be errors introduced during the digitizing and geo-referencing process. In most cases, errors in the DRG are small compared with sources of error in the original map graphic. The RMS error for\nthis map is: 7.79279 meters. RMS (Root Mean Square ) Error is defined as: A measure of the difference between locations that are known and locations that have been interpolated or digitized. RMS error is derived by squaring the differences between known and unknown points, adding those together, dividing that by the number of test points, and then taking the square root of that result. The lack of greater accuracy is largely a result of distortions in the original paper map document prior to scanning."}]}},"files":[{"description":"","label":"TIFF","restricted":false,"version":1,"datasetVersionId":17419,"dataFile":{"id":2332869,"persistentId":"","filename":"TIFF","contentType":"application/octet-stream","friendlyType":"Unknown","filesize":0,"description":"","storageIdentifier":"http://hgl.harvard.edu:8080/HGL/jsp/HGL.jsp?action=VColl&VCollName=USGS15MA_FRAMINGH_1884","rootDataFileId":-1,"md5":"","checksum":{"type":"MD5","value":""},"tabularData":false,"creationDate":"2015-04-08","publicationDate":"2011-12-12","lastUpdateTime":"2011-12-13T18:00:40Z","fileAccessRequest":false}}]}}}
