W9 Vector II

PART III: Process Summary Details

1)      Copy data from R drive to S drive and unzipped it

2)      Open ArcMap and add the roads.shp layer

3)      Open ArcToolbox, select buffer, located under Proximity in the Analysis Tools section

4)      Under Input Features, select Roads, Output Feature Class, navigate to data folder and save as Roads_Buffer.shp, Linear unit will be 300 Meters, and change Dissolve Type to All, select OK

5)      Save map as Vector_II_BED.mxd

6)      Turn off Roads and roads_buffer layers

7)      Add water.shp to map

8)      Open attribute table, under Table Options, click on Add field, name it “buffdist” and Short Integer as type, click OK

9)      Highlight all Lake under type by left-click and drag mouse on left side of table, right-click on the buffdist column and select Field Calculator

10)  In buffdist= box, enter 150, hit OK

11)  Highlight River under type by left-click on left side of table, right-click on the buffdist column and select Field Calculator

12)  In buffdist= box, enter 500, hit OK

13)  Clear selection

14)  Open ArcToolbox, select buffer, located under Proximity in the Analysis Tools section

15)  Under Input Features, select Water, Output Feature Class, navigate to data folder and save as Water_Buffer.shp, Field will be buffdist, and change Dissolve Type to List, in Dissolve Field(s) box, check buffdist,  select OK

16)  Turn on all layers in map

17)  Open Python Window

18)  Type ‘import arcpy’, hit the enter key

19)  Type ‘arcpy.’, include period, start typing ‘Buffer’, a dropdown will appear, select Buffer_analysis by double-clicking

20)  Type an open parenthesis, ie Buffer_analysis( a dropdown menu will appear with available selections, select Roads

21)  Place a comma after Roads, then double quotes around the full path of the output file, another comma

22)  Next will be the buffer distance ie “100 Meters”, it must be a number and then the units in plural with a capital letter, another comma

23)  The last three fields will appear in a dropdown menu in succession “Full”, “ROUND”,”ALL”, ending with a closed parentesis

24)  The whole line should look like this:  arcpy.Buffer_analysis("Roads", "your path\BufferRoads100m","100 Meters", "FULL", "ROUND", "ALL")

25)   Hit Enter to run the script

26)  The result should say <Result 'your path\BufferRoads100m.shp'>

27)  The new layer will appear in your map

28)  Turn off the new layer

29)  Open attribute table for the Water_Buffer layer, under Table Options, click on Add field, name it “insd_wbuf” and Short Integer as type, click OK

30)  right-click on the insd_wbuf column and select Field Calculator, in insd_wbuf = box, enter 1, hit OK

31)  Open attribute table for the Roads_Buffer layer, under Table Options, click on Add field, name it “insd_rbuf” and Short Integer as type, click OK

32)  right-click on the insd_rbuf column and select Field Calculator, in insd_rbuf = box, enter 1, hit OK

33)  To run the union overlay, open ArcToolbox, expand Analysis Tools and select Overlay toolset

34)  Select Union with the following parameters; Input Features, select Water_Buffer and Roads_Buffer, name the output Buffers_Union

35)  Under the JoinAttributes select ALL, leave Gaps Allowed checked, click OK

36)  Using Select By Attributes under the Selection menu, use Buffers_Union as the Layer, leave Method: Create a new selection and SELECT *FROM Buffers_Union WHERE is the following equation "insd_rbuf" = 1 AND "insd_wbuf" = 1, hit OK

37)  Export selected features by right-clicking on Buffers_Union, selecting Data, the Exporting Data

38)  In the Export: dropdown, be sure Selected features is selected, and make the shapefile name buffer_union_export, click OK

39)  Add new layer to map

40)  Add conservation_areas layer to map

41)  Open ArcToolbox, expand Analysis Tools and select Overlay toolset, select Erase with the following parameters; Input Features, select buffer_union_export, Erase Features, select conservation_areas, name the output possible_sites

42)  Open ArcToolbox, expand Data management Tools and select Features toolset, select Multipart To Singlepart with the following parameters; Input Features, select possible_sites, name the output possible_sites_single.shp to convert to single part layer

43)  Open the possible_sites_single attribute table and add a new field called “Area”, type ‘double’

44)  Right-click on Area, use Calculate Geometry to compute area in square meters

45)  Switched to Map View to finish map

46)  Added title, legend, north arrow, scale bar, etc to map

47)  Saved map one last time as Vector_II_BED 1.mxd

48)  Exported map as Vector_II_BED 1.jpg

49)  Uploaded items to appropriate locations
