Module 2 Process Summary

Map 1

After opening the 7KGY10042_060.tif file in ArcMap, I never saw the window that would ask me if I want to build pyramids. I opened the image, and studied the aerial for exceptionally bright features. I selected a small white feature within the upper right-side quadrant of the photograph as my object of focus. It is an elongated rectangular building, among a cluster of similar looking buildings.

*I have decided to select small features for the first part of this lab, because I thought that the shade tones were most defined in smaller land marks.

I proceeded to draw a polygon around my feature with the drawing tool. I made the outline bright pink and left the inside of the feature hollow. Afterwards, I repeated the process four more times as directed and selected the following features to correspond to the brightness criteria:

Light: A T-shaped building along a major road in the upper right-side quadrant. (Close to the center of the map.)

Medium: A rectangular medium-grey feature in an empty lot, by a small woodland. Located within the upper right quadrant of the map.

Dark: A small, rectangular building feature in the upper-right quadrant of the map.

Very Dark: A small semi-rectangular body of water located off a road in the lower left side of the quadrant.

I converted my drawn outlines into a shapefile as the instruction suggested, and deleted the drawings from my aerial photograph all together. I began the editing session by right-clicking my “Tone” shapefile in the table of contents, and named all the features according to the appropriate tone. Afterwards, I exited the editing session.

I repeated the above steps to create five texture features based on the following criteria:

Very Fine: A body of water in the lower-left quadrant of the photograph.

Fine: A field in the bottom center of the map.

Mottled: A small field in the bottom left quadrant of the photograph.

Coarse: A patch of woodland in the left center of the photograph.

Very Coarse: A rectangular, semi-overgrown block located in the bottom-right of the map.

Afterwards, I simply added a few of the essential map elements to my work and exported as a JPEG file.

Map 2

For the second assignment, I searched for three features that could be recognized mainly by their shape and size. Afterwards, I marked them with a green point using the drawing tool and converted them to a set of features like I have in the previous exercise. The features selected were;

1.       A docking pier

2.       A swimming pool

3.       A parked truck

I created two more sets of features in the same fashion, according to the lab instructions. I have located three features that were recognizable primarily by the shape of their shadow, and marked them with blue points. The features were;

1.       A water tower

2.       A cluster of trees

3.       A directional road sign

(The last one is the least certain, due to its specific location in front of a building. But I feel that an argument can be made based on the shape of the shadow alone.)

Finally, I have located two features that could be identified based on their pattern. (Other features closely associated.) They were;

1.       A school (based on the size, shape as well as the driveway up front that seems to be designed for buses.)

2.       A residential neighborhood (Identified by many medium-sized buildings located next to one another in rows, and right along streets.)

Once all the features were labeled, I finalized the project by adding a few essential map elements and exporting it as a JPEG file.
