OPEN THE ATTRIBUTE TABLE OF LAND USE (WATERSHED) LAYER <ul><li>-Change the color of municipality layer to “No color(Transparent)” </li></ul><ul><li>- Change the color of Municipality boundary to distinguish that of a watershed layer, for example, to “red color” </li></ul>
11.
CHECK IF THE FIELD CONSISTS OF NOMINAL VARIABLES OR NOT(ORDINAL/NUMERIC?...) <ul><li>(ex) Field Type02 -> Urban/Forest… -> Nominal variable)-> Maps by Categories </li></ul>
22.
CLIP <ul><li>Geo processing->clip->set the right directory(a location where you want to save a file) </li></ul><ul><li>Cookie dough (input feature) : Watershed layer (Land Use layer) </li></ul><ul><li>Cookie cutter(Clip feature) : New Brunswick layer (the one you exported from municipal boundary layer) </li></ul><ul><li>(The data in attribute table which is contained in Watershed layer(Land Use layer) will be conveyed to the newly clipped layer after you clip watershed layer with New Brunswick layer) </li></ul>
24.
SELECT THE DIRECTORY (LOCATION WHERE YOU SAVE THE FILE)
25.
INPUT FEATURE(WATERSHED LAYER)/OUTPUT FEATURE(NEW BRUNSWICK LAYER) AND CLICK “OK”
26.
NEXT STEP : NEW BRUNSWICK LAND USE CHANGE <ul><li>Export Land Use Layer(watershed layer) with the boundary of New brunswick boundary layer from municipal boundary layer by “Clip tool” </li></ul><ul><li>2. Within clipped-New Brunswick Land use layer(watershed layer), select the land use change area (Field Name : CHANGE07) by using “Select by attribute “ </li></ul><ul><li>Fomulas : “CHANGE07”=1 </li></ul><ul><li>Right click on the layer of NB land use and export the feature as a shapefile while selection on the land use change is activated, then you will get the map of land use change in 2007 WITHIN New Brunswick. </li></ul><ul><li>3. In this exported map(Land Use Change07 within NB), we want to check how many residential areas are included. </li></ul><ul><li>Open Attribute table, and Sorting data by clicking the field of Land use by dragging individual cases in “the attribute table” – Use Sorting function in the attribute table – </li></ul><ul><li>4. Calculate the Acres of selected features : Open the attribute table –select the variables/cases/features that you want to calcuate – Right click on the ‘ACRES” field – Click “Statistics ” </li></ul>
31.
SELECT RESIDENTIAL AREA WITHIN LAND USE CHANGE FEATURES. <ul><li>Click the layer for land use change that you just exported-> Open attribute table -> sort -> drag (select the all residential area) -> export a data again. </li></ul>
32.
SELECT RESIDENTIAL AREA IN THE ATTRIBUTE TABLE.
34.
CALCULATE ACRES : <ul><li>1. Select the cases that you want to calculate </li></ul><ul><li>2. Right click Acres – go to “statistics” </li></ul><ul><li>3. Information available </li></ul><ul><li>Counts (Number of cases you chose) </li></ul><ul><li>Sum / Minimum/Maximum/Standard deviation/… </li></ul>

EXAMPLE OF LAND USE CHANGE ANALYSIS <ul><li>Land use change around Raritan river waterbody – related to contamination. </li></ul><ul><li>1. Clip certain area of interests </li></ul><ul><li>2. buffer the river </li></ul><ul><li>< Applications > </li></ul><ul><li>- Mapping Land use change within municipalities </li></ul><ul><li>- The impact of Municipal policies on Land use, </li></ul><ul><li>- The analysis of land preservation – its comparison with other municipalities and so on </li></ul>
