Cartogram-Energy Consumption

Another variable is used to graph area. The size of each area represents the size of the variable that is being maped; it is distorted to match the value of the variable. I found this one to be quite interesting .. Energy consumption!! What a hot topic today with our current gas prices. The map on the left is a normal world map which the cartogram on the right represents energy consumption. The USA looks kind of puffy and swollen!!

Remote Sensing-Google Earth Project

I visited the MODIS Active Fire Mapping Program ( MODIS stands for Moderate Resolution Imaging Spectroradiometer. This is the sensor used on the satellite. MODIS is a multi-spectral sensor. The spatial resolution of MODIS is 250 m (band 1-2); 500m (band 3-7) and 1000m (bands 8-36)
( These measurements indicate longer wavelengths because they are in meters. MODIS detects over a wide range of the spectrum (multispectral). The referenced brochure details each band .. land/cloud properties bands 3-7; ocean band 8, sky band 17, etc.

This kml displays the United States with symbology representing the fire detections; I zoomed in to the Arizona area to see the geography of the area. The google image displays 1 km MODIS fire detections for the past 12 hours, 12-24 hours and previous 6 days; this was downloaded from Google Earth on Tuesday, June 24th. (NOTE: MODIS completes an image of the earth every 2 days). The Incident Management Team is located north of the Yuba River and all fire incidents occur south of the river.

State of Florida Topographic Map

Downloaded from, this is a USGS map which depicts the topography of Florida. Florida is relatively flat in terms of signficant changes in elevation; however, since the state is a peninsula surrounded by water, this map accurately visualizes the depths of the continental shelf and the waters of the Gulf of Mexico and the Atlantic Ocean.

Dick's Map - Planimetric Map

This map was retrieved from a blog and like the individual who posted it, I found the map be an interesting and unusual method of providing typical street map data. The star on the map identifies the location of Dick's Sporting Goods Store. Although the map is typical of most plainmetric maps it is the display of the map on a support pole that makes it most interesting. I don't think a typical map would stand out quite as much in a retail establishment. This map was retrieved from Dick's Map, Tuesday, May 27, 2008.
