Rajinder holds a Master of Science degree in Geoinformatics and a Bachelor of Science degree in Urban &amp; Regional Planning.","sameAs":["https:\/\/www.linkedin.com\/in\/rajnagi\/"],"jobTitle":"Principal GIS Engineer","worksFor":"Esri Inc.","url":"https:\/\/www.esri.com\/arcgis-blog\/author\/rajnagi"}]}},"text_date":"February 6, 2015","author_name":"Rajinder Nagi","author_page":"https:\/\/www.esri.com\/arcgis-blog\/author\/rajnagi","custom_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/08\/Newsroom-Keyart-Wide-1920-x-1080.jpg","primary_product":"ArcGIS Living Atlas","tag_data":[{"term_id":24101,"name":"Africa","slug":"africa","term_group":0,"term_taxonomy_id":24101,"taxonomy":"post_tag","description":"","parent":0,"count":8,"filter":"raw"},{"term_id":22951,"name":"ArcGIS Content","slug":"arcgis-content","term_group":0,"term_taxonomy_id":22951,"taxonomy":"post_tag","description":"","parent":0,"count":331,"filter":"raw"},{"term_id":24111,"name":"aspect","slug":"aspect","term_group":0,"term_taxonomy_id":24111,"taxonomy":"post_tag","description":"","parent":0,"count":12,"filter":"raw"},{"term_id":22801,"name":"bathymetry","slug":"bathymetry","term_group":0,"term_taxonomy_id":22801,"taxonomy":"post_tag","description":"","parent":0,"count":34,"filter":"raw"},{"term_id":24121,"name":"Caribbean","slug":"caribbean","term_group":0,"term_taxonomy_id":24121,"taxonomy":"post_tag","description":"","parent":0,"count":4,"filter":"raw"},{"term_id":24131,"name":"digital elevation model (DEM)","slug":"dem","term_group":0,"term_taxonomy_id":24131,"taxonomy":"post_tag","description":"","parent":0,"count":32,"filter":"raw"},{"term_id":24141,"name":"elevation","slug":"elevation","term_group":0,"term_taxonomy_id":24141,"taxonomy":"post_tag","description":"","parent":0,"count":57,"filter":"raw"},{"term_id":24151,"name":"esri_earth","slug":"esri_earth","term_group":0,"term_taxonomy_id":24151,"taxonomy":"post_tag","description":"","parent":0,"count":9,"filter":"raw"},{"term_id":24161,"name":"Europe","slug":"europe","term_group":0,"term_taxonomy_id":24161,"taxonomy":"post_tag","description":"","parent":0,"count":5,"filter":"raw"},{"term_id":24981,"name":"hydro","slug":"hydro","term_group":0,"term_taxonomy_id":24981,"taxonomy":"post_tag","description":"","parent":0,"count":204,"filter":"raw"},{"term_id":24171,"name":"land","slug":"land","term_group":0,"term_taxonomy_id":24171,"taxonomy":"post_tag","description":"","parent":0,"count":8,"filter":"raw"},{"term_id":40161,"name":"Living Atlas of the World","slug":"living-atlas-of-the-world","term_group":0,"term_taxonomy_id":40161,"taxonomy":"post_tag","description":"","parent":0,"count":392,"filter":"raw"},{"term_id":24181,"name":"multi-directional hillshade","slug":"multi-directional-hillshade","term_group":0,"term_taxonomy_id":24181,"taxonomy":"post_tag","description":"","parent":0,"count":9,"filter":"raw"},{"term_id":24191,"name":"NAGI fusion method","slug":"nagi-fusion-method","term_group":0,"term_taxonomy_id":24191,"taxonomy":"post_tag","description":"","parent":0,"count":9,"filter":"raw"},{"term_id":24201,"name":"NASA","slug":"nasa","term_group":0,"term_taxonomy_id":24201,"taxonomy":"post_tag","description":"","parent":0,"count":10,"filter":"raw"},{"term_id":22901,"name":"National Government","slug":"national-government","term_group":0,"term_taxonomy_id":22901,"taxonomy":"post_tag","description":"","parent":0,"count":255,"filter":"raw"},{"term_id":22821,"name":"oceans and maritime","slug":"oceans-and-maritime","term_group":0,"term_taxonomy_id":22821,"taxonomy":"post_tag","description":"","parent":0,"count":102,"filter":"raw"},{"term_id":26221,"name":"open data","slug":"open-data","term_group":0,"term_taxonomy_id":26221,"taxonomy":"post_tag","description":"","parent":0,"count":218,"filter":"raw"},{"term_id":24211,"name":"Slope","slug":"slope","term_group":0,"term_taxonomy_id":24211,"taxonomy":"post_tag","description":"","parent":0,"count":13,"filter":"raw"},{"term_id":24221,"name":"South America","slug":"south-america","term_group":0,"term_taxonomy_id":24221,"taxonomy":"post_tag","description":"","parent":0,"count":3,"filter":"raw"},{"term_id":23391,"name":"spatial analytics","slug":"spatial-analytics","term_group":0,"term_taxonomy_id":23391,"taxonomy":"post_tag","description":"","parent":0,"count":344,"filter":"raw"},{"term_id":24231,"name":"SRTM","slug":"srtm","term_group":0,"term_taxonomy_id":24231,"taxonomy":"post_tag","description":"","parent":0,"count":4,"filter":"raw"},{"term_id":24241,"name":"tinted hillshade","slug":"tinted-hillshade","term_group":0,"term_taxonomy_id":24241,"taxonomy":"post_tag","description":"","parent":0,"count":9,"filter":"raw"},{"term_id":24251,"name":"topography","slug":"topography","term_group":0,"term_taxonomy_id":24251,"taxonomy":"post_tag","description":"","parent":0,"count":20,"filter":"raw"}],"category_data":[{"term_id":23771,"name":"3D Visualization &amp;
