VECTOR OVERLAY ANALYSIS
i.  Insert all provided spatial data (land-use, road and elevation
ii.  Add column in landuse.shp and write as landuse_Perlis.
iii.  Use DISSOLVE tool to create a single polygon.
iv.  Use the single polygon of landuse as boundary and use EXTRACT BY MASK to select the DEM Perlis region only.
v.  Use CLIP tool for selecting the Perlis Road only.
vi.  Use BUFFER tool to delineate the zoning area of road in 100m and 200m. It should be in two different layer.
vii.  Use ERASE tool to eliminate the zone of 100m and to preserve area within range 100-200m.
viii.  Use INTERSECT tool to identify the landuse type within 100m for the centre of road and within 100-200m. Specify the landuse involved.
ix.  Create grid polygon by create new polygon. Open catalog pane and create new feature class/ shapefile. Save. Digitise big polygon cover the landuse. Then, use  to split into 4 different polygon. Add new column as Zone. Then fill in A, B, C,D.
x.  Split the landuse into 4 different area. Use SPLIT tool. Try to see what will happen to your data.
xi.  Use MERGE tool to combine all layers into single polygon.
xii.  Use RECLASSIFY to classify the DEM (elevation) into 3 classes: i) < 10m, ii) 10 – 20m and iii) 20-30m, iv) >30m
xiii. Use RECLASSIFY to classify the Slope_Degree into 5 classes: i) < 0.1, ii) 0.1 – 0.5, iii) 0.5-0.10, iv) 0.10-1, v) 1-2, vi) >2

1.  Mask peninsular DEM
2.  Create Contour. Choose contour too. Add in contour interval by 5 or 10m. Base is 0
3.  Label the contour line. Right click layer and choose label properties and language is VB. Choose label to display. Then, choose label.
4.  Choose Create TIN. Apply contour height and setting mass point.
5.  Look the result.
6.  Choose raster to TIN tool. Look into the result.
7.  Compare the two results.
8.  To create profile, create new feature class (line). Save
9.  Choose stack Profile tool. Input is line and profile target are DEM.
10.  To View 3D, go to VIEW, choose to convert to local scene. Your screen will create new layout as Map_3D.
11.  Click navigator and show full control. Try to move the centre of circle and look the movement.
12.  New task. Download Landsat peninsular Malaysia dan drape the image on TIN.

1. Map scale
- From the map given, there is no map scale included. Map scale are important to identify the real measurement between on the map and on the ground.
Solution: Every GIS Analyst must have to put the map scale before publish it to the client.

2. Coordinate
- There is no north arrow on the map, so it shows that the image was not register properly with the exact coordinate. This will make the map might be wrong with the orientation or projection.
Solution: First thing before we start digitize, we must register the image with the right coordinate and position.

3. Digitising
- From the image given, we can see that the map not digitize properly.
Solution: After we digitize the map, we have to edit some features to prevent the map looks terrible.

4. Multiple Input
- The figure above shows that the map was digitize with a confusing line. From my view, there is a double layer when the person digitize it. The line with the red color might overlap the black line that make the map looks confusing.
Solution: When we digitize the map we must arrange the layer to make sure the digitize would not confuse the client or who see the map.

1.      Describe the skills required to be as GIS analyst.
- The skills required to be as GIS analyst are, they must good in interpreting data before do the mapmaking. This is because doing a map are used to solve the problem. If we not good in interpreting data, the map might not deliver the right information to the client.

2.      Explain the importance of spatial analysis in real world modeling.
- The importance of spatial analysis in real world modeling

3.      Why GIS is essential to help on decision making on climate change forecasting?
