LAB 4

PART 1: More with Projections

 

Layers:

Caves(points), 

Streams(lines), and 

Lab4_Mable(Polygons). 

I opened ArcCatalog10 and went to the Y drive (Y:\) at the Catalog Tree which shows all the courses.  Under "courses_pkahn", I see the contents; Caves, Marbles and Streams.  I had to change all of their XY coordinate systems to North America Lambert Conformal Conic, then  save/copy all of those files to my own personal drive (U:\).  After successfully copying them to my drive, I open them all, or drag them all from my personal drive in ArcCatalog to ArcMap.

PART 2: Data formats

1. The types of vectors are dots/points, lines, shapes/polygon.

2. You can save these files on to your personal drive(s).  You may also export the map if you want to save the image of it by turning it into a jpeg file.

5. These ; .shp .shx .sbn .prj .dbf are different types of file formats. shp. is the feature geometry. shx. is  a positional index of the  geometry to access seeking forwards and backwards fast. sbn. is the spatial index. pjr.  is coordinate system and projection information. dbf. -columnar attributes for each of the shape.
