This panel discussion, entitled “A Conversation with NGA Leadership,” conducted Wednesday June 24th, at GEOINT 2015 had the flavor of an inside meeting, according to USGIF CEO Keith Masback, who joked that “we cleverly tricked about 1,500 people into coming to a staff meeting.”

TopoView provides one of the USGS’s most important and useful products, the topographic map, in a way that is easy to use, accessible and provides wonderful historical map data.
In 1879, the USGS began to map the Nation’s topography. Just like in a lot of modern mapping, this topographical mapping was done at different levels of detail, as needed to support various land use, exploration and other purposes. The collection of maps deepened and expanded as the years passed, with the USGS producing new map versions of each area. The most current maps are available from The National Map. For those users who need historical reference maps, TopoView shows the many and varied older maps of each area. TopoView also takes into account the fact that the names of some natural and cultural features have changed over time, and the ‘old’ names can be found on these historical topographic maps.
According to USGS materials, this interface was created by the National Geologic Map Database project (NGMDB), in support of topographic mapping program managed by the National Geospatial Program (NGP). Geologic mapping and topographic mapping at the USGS have a long tradition together (see 1888 report). The NGMDB project is proud to assist the NGP in bringing these maps to the Web.
TopoView is packed with new features as well as downloadable file formats such as jpeg, GeoTIFF, and KMZ. The maps shown through topoView are from the USGS’s Historical Topographic Map Collection (HTMC). The goal of this scanning, which started in 2011, is to provide a digital repository of USGS 1:250,000 scale and larger (more detailed) maps printed between 1884 (the inception of the topographic mapping program), and 2006. Currently, there are more than 178,000 maps in the HTMC. The NGP is accurately cataloging and creating metadata to accompany high-resolution, georeferenced digital files of each of these printed maps. At present, these maps are offered as GeoPDFs, through The National Map and the USGS Store. However, additional formats are now being offered for evaluation and use through topoView to include:
Esri User Conference Morning Plenary Session Covers Geoenlightenment, Web GIS, Story Maps, ArcGIS Earth and Much MoreTuesday, July 21st, 2015
With the theme, “Applying geography everywhere,” Jack Dangermond, president of Esri, definitely covered all the pertinent topics of the day. The Esri User Conference held annually in San Diego, kicked off Monday with approximately 16,000 in attendance, which could be amply felt in the halls and the morning plenary session.
GISCafe will be exhibiting at the Esri User Conference 2015 in San Diego this coming week at Booth #616. Our president, Sanjay Gangal , will be recording video interviews at the booth. Editor of GISCafe and GISCafe Voice, Susan Smith, will be onsite covering the conference. Come by to participate in the video interviews or for a chance to win a KindleFire!
