GIS Data Formats, Design and Quality - University of California, Davis About this course: In this course, the second in the Geographic Information Systems (GIS) Specialization, you will go in-depth with common data types (such as raster and vector data), structures, quality and storage during four week-long modules: Week 1: Learn about data models and formats, including a full understanding of vector data and raster concepts. You will also learn about the implications of a data’s scale and how to load layers from web services. Week 2: Create a vector data model by using vector attribute tables, writing query strings, defining queries, and adding and calculating fields. You'll also learn how to create new data through the process of digitizing and you'll use the built-in Editor tools in ArcGIS. Week 3: Learn about common data storage mechanisms within GIS, including geodatabases and shapefiles.

U.Va. Scholars Receive Federal Grant To Develop Tool for Collecting Maps Online Humanities scholars interested in maps and what they say about how their creators viewed the world will soon have a new digital tool at their disposal, courtesy of two University of Virginia scholars. S. Max Edelson, an associate history professor in the College of Arts & Sciences, and Bill Ferster, a senior scientist at the Curry School of Education, recently received a $297,116 federal grant to develop a program they call "MapScholar."

Stats, Maps n Pix: The Global Human Settlement Layer: an amazing new global population dataset At the recent Habitat III conference on housing and sustainable development in Quito, Ecuador (17-20 October 2016) the European Commission launched a new Global Human Settlement (GHS) dataset. That's what this post is about. Before that, here are some basic data details - Landsat data from 1975, 1990, 2000 and 2014 were processed and analysed in order to produce three different GHS products: one on population (GHS-POP), one on built-up areas (GHS-BUILT) and one city model dataset (GHS-SMOD). But this is already getting too technical, so let's look at some maps - I've just created a few in 3D for fun in order to give you an idea of what the population dataset looks like. Each image below uses the 250 metre resolution one (there is also a 1km cell version for population).
40 maps that explain the Roman Empire by Timothy B. Lee on August 19, 2014 Two thousand years ago, on August 19, 14 AD, Caesar Augustus died. He was Rome's first emperor, having won a civil war more than 40 years earlier that transformed the dysfunctional Roman Republic into an empire. Under Augustus and his successors, the empire experienced 200 years of relative peace and prosperity. Here are 40 maps that explain the Roman Empire — its rise and fall, its culture and economy, and how it laid the foundations of the modern world.

MapMaker Interactive Welcome to the MapMaker Interactive This tutorial explains how to explore National Geographic Education's interactive GIS mapping tool and tools for customizing outline maps for print. Use the zoom bar to go from a world view to a local view (or in cartographic terms, from a large scale to a small scale). If you zoom out to a world view, you will see that the map is in a Mercator projection. Use the location menus at the top to zoom from a world view to a continent, country, or other region. Identify your geographic position on the map using the latitude and longitude display at the bottom left.
