Preliminary Data Observations
<What data we have here>
Steps:
- Align to Geometry and Coordinate Reference System for all files: EPSG:3828
- Extracting each POI from the different shp files
- Formation of polygons for each branch to align to ppt slides' trade area
- Creation of competitors' POI
- Aggregation of count of each POI to each trade area
- Investigation on areas not covered by trade area
- Data pre-processing for Sales Data
- Aggregating Sales Data with each branch
- Regression Analysis
1. Geometry and Coordinate Reference System
Every qgis file created have to align to the same reference system used by Taiwan Maps for accuracy and unit measurement.
Information on 3828 Reference system: https://epsg.io/3828
3. Formation of polygons for each branch to align to ppt slides' trade area
4. Creation of competitors' POI
5 Competitors are identified and they are Dominos Pizza, Napolean Pizza, Mcdonalds, KFC and MosBurger. These data points are crucial in our analysis as they may have a correlation with the sales data. Hence, these competitors branches location have to be extracted from "Restaurant 5800".
After extraction, they are exported as layers in the geopackage to be used for aggregation.
5. Aggregation of count of each POI to each trade area (Script)
It is an exhausting task to aggregating each of the POIs into each trade area using the "Count Points in Polygon" tool.
The batch processing tool was tried but it is unable to append each newly created POI into an existing geopackage. Hence, a python script was written and it ran under QGIS's Python Console. It utilised "processing.run('qgis:countpointsinpolygon', parameters)" function, an inbuilt function by QGIS.
Learn more about the function here: https://docs.qgis.org/2.8/en/docs/user_manual/processing_algs/qgis/vector_analysis_tools/countpointsinpolygon.html
After the aggregation of POIs into each trade area, below is the screenshot of the columns for a particular trade area.
6. Investigation on areas not covered by trade area
As we observe the generated trade areas, it seems that there are some areas that are not covered by any of the branches. Hence, we decided to anaylse these areas.
In the above figure, the uncovered area is 大安森林公园 which is a park. Hence, it is explainable that such locations should not be covered in the delivery area.
In the above figure, we do see buildings that are not in any trade area. Therefore, this uncovered area may have be omitted and should be fulfilled by one of the branches.
