GIS4035 - Remote Sensing and Photo Interpretation - Module 6

.   I tried running the clipped aerial through several different filters in ERDAS obtained following results;

a.      11x11 LowPass – image was very blurry and difficult to interpret.

b.      3x3 Edge Enhance – image became very uniformly grey, and the lines became darker and quite pronounced.

c.       5x5 High Pass – Image became very dark, and only larger features became all grey in color. Very difficult to read.

d.      3x3 Haze Reduction – Fairly readable, but the dark lines become awfully thick on the left side of the image.

e.      3x3 Sobel – Image became monochromatic, and much too dark.

2.  After many attempts, I decided to use my initial ‘sharpen1’ file from the early stage of the assignment. Put the finishing touches on the photo in ArcMap

The initial raster was modified with ERDAS Imagine. A new column was added to the attribute table, that allowed for the automatic calculation of area covered by each color category. The layout as well as the essential map elements were later added in ArcMaps, and the image was exported as a JPEG.
