Coordinates of selected controlpoints measured on existing 72-and 15-minute standard maps providesufficient accuracy for any space imaging system thus far defined.Thisprocedure references the points to accepted horizontal and verticaldatums.Maps as small as 1:250,000 scale can be used as source materialfor coordinates,but to maintain the desired accuracy,maps of  \n1:100,000 and larger scale should be used when available.  \n# GROUND CONTROL REQUIREMENTS FORPRECISION PROCESSING OF ERTS IMAGES\n\nbyThomas C.Burger  \nINTRODUCTION  \nThe first Earth Resources Technology Satellite(ERTS-1)wassuccessfully launched by NASA on July 23,1972.The predicted 900 km(492 n.mi.)near-polar orbit was achieved to near perfection.  Thesatellite is sun-synchronous;that is,at any given part of an orbit,local sun time(approximately 10 AM)remains the same.The sensorson board produce multispectral images of the earth for use in earthresources investigations and in 18-day cyclic coverage provide aredundancy of scenes for studies of time-variant phenomena.  \nWith regard to geometric properties,the most precise sensorsaboard are the three return-beam vidicon(RBV)cameras configuredto focus on the same scene covering an area of 185 x 185 km(100 x 100  \nn.mi.)in three spectral bands--green,red,and near infrared.  Themultispectral scanner(MSS),also aboard,provides coverage of the samescene in four spectral bands,imaging in a continuous 185-km swath alongthe orbital ground track.  The MSS produces better spectral imagery thanthe RBV but of lower geometric quality.  \nThe image data is transmitted to earth over two wideband S-banddata links.On the ground it is reconstituted using an electron beamrecorder(EBR)on 70-mm film in frames for each spectral band.Theseframes appropriately annotated are the so-called bulk(or system  \ncorrected)images.Selected scenes from the bulk imagery are precision-processed(scene-cor","cbCaiaytjhaulphc","https://ap.wps.com/l/cbCaiaytjhaulphc","pdf",2894602,1,15,"Spanish","es",110,"# Resumen\n# Abstract\n# INTRODUCTION\n# POINT SELECTION","[{\"question\":\"¿Qué permite el satélite ERTS-1 para el procesamiento de precisión?\",\"answer\":\"Con el vuelo exitoso del ERTS-1 se dispone de imágenes tomadas desde altura orbital, utilizables para elaborar productos cartográficos y realizar correcciones radiométricas y geométricas mediante procesamiento de precisión.\"},{\"question\":\"¿Por qué es clave la selección de puntos de apoyo en el procesamiento?\",\"answer\":\"Para mantener el error de ubicación por debajo de 100 metros, los puntos de apoyo deben seleccionarse cuidadosamente y deben verse claramente y con definición en sus coordenadas X e Y.\"},{\"question\":\"¿Qué escalas de mapas se recomiendan como fuentes para conservar la exactitud?\",\"answer\":\"Mapas tan pequeños como 1:250.000 pueden usarse como fuente, pero para conservar la exactitud deseada deben usarse mapas de 1:100.000 o mayores cuando estén disponibles.\"}]","REQUISITOS DE CONTROL TERRESTRE PARA LA ELABORACIONPRECISA DE IMAGENES ERTS | PDF",1791856866,23,{"code":4,"msg":73,"data":74},"ok",{"site_id":66,"language":65,"slug":75,"title":55,"keywords":76,"description":56,"schema_data":77,"social_meta":132,"head_meta":134,"extra_data":136,"updated_unix":70},"ground-control-requirements-for-precision-processing-of-erts-images","",{"@graph":78,"@context":131},[79,95,114],{"@type":80,"itemListElement":81},"BreadcrumbList",[82,86,89,92],{"item":83,"name":84,"@type":85,"position":62},"https://docshare.wps.com","Home","ListItem",{"item":87,"name":9,"@type":85,"position":88},"https://docshare.wps.com/es/document/",2,{"item":90,"name":27,"@type":85,"position":91},"https://docshare.wps.com/es/document/investigación-e-informes/",3,{"item":93,"name":55,"@type":85,"position":94},"https://docshare.wps.com/es/document/ground-control-requirements-for-precision-processing-of-erts-images/565652/",4,{"url":93,"name":55,"@type":96,"image":97,"author":102,"headline":55,"publisher":104,"fileFormat":107,"inLanguage":65,"description":56,"dateModified":108,"datePublished":108,"encodingFormat":107,"isAccessibleForFree":109,"interactionStatistic":110},"DigitalDocument",{"url":98,"@type":99,"width":100,"height":101},"https://docshare.wps.com/thumbnails/ground-control-requirements-for-precision-processing-of-erts-images/565652.png","ImageObject",300,407,{"name":53,"@type":103},"Person",{"url":83,"name":105,"@type":106},"DocShare","Organization","application/pdf","2026-10-13",true,{"@type":111,"interactionType":112,"userInteractionCount":4},"InteractionCounter",{"@type":113},"ViewAction",{"@type":115,"mainEntity":116},"FAQPage",[117,123,127],{"name":118,"@type":119,"acceptedAnswer":120},"¿Qué permite el satélite ERTS-1 para el procesamiento de precisión?","Question",{"text":121,"@type":122},"Con el vuelo exitoso del ERTS-1 se dispone de imágenes tomadas desde altura orbital, utilizables para elaborar productos cartográficos y realizar correcciones radiométricas y geométricas mediante procesamiento de precisión.","Answer",{"name":124,"@type":119,"acceptedAnswer":125},"¿Por qué es clave la selección de puntos de apoyo en el procesamiento?",{"text":126,"@type":122},"Para mantener el error de ubicación por debajo de 100 metros, los puntos de apoyo deben seleccionarse cuidadosamente y deben verse claramente y con definición en sus coordenadas X e Y.",{"name":128,"@type":119,"acceptedAnswer":129},"¿Qué escalas de mapas se recomiendan como fuentes para conservar la exactitud?",{"text":130,"@type":122},"Mapas tan pequeños como 1:250.000 pueden usarse como fuente, pero para conservar la exactitud deseada deben usarse mapas de 1:100.000 o mayores cuando estén disponibles.","https://schema.org",{"og:url":93,"og:type":133,"og:title":55,"og:site_name":105,"og:description":56},"article",{"robots":135,"canonical":93},"index,follow",{"doc_id":51,"site_id":66}]
