Lab 2 Projections


Lab 2 had us experimenting with projections.  In this lab I had to choose an US state and choose an appropriate projection to display it.  I chose Texas as my study area.  Texas has 5 state planes and 3 UTM’s so I looked for a custom coordinate system to better display state wide data.  ESRI has several custom Albers and Lambert based projections which are good for showing study areas with an east west extent like Texas.  I chose NAD_1983 2011_Texas_Centric_Mapping_System_Lambert which is a Lambert Conformal Conic projection.  Lambert projections are good for navigational purposes which made a good choice for a map showing Texas’s major roads.  Created by Ray Eslinger in Nassau County Fl.
