Flood Emergency Planning 2nd Assignment

2 Instructions
To complete this assignment, you need to build a Python application. Your task is to create a Python program named ‘main.py’ that does what explained in the following subsections. To do this, you are allowed to use only the packages presented in the module.
The first 5 tasks will award you a total of 80 marks. The 6th task (10 marks) is designed to test your ability to carry out your own research in order to solve it. Finally, the 7th tasks is a creativity task that can award you 10 additional marks for the development of additional unspecified features.
2.1 Task 1: User Input
The application should ask the user to input their current location as a British National Grid coordinate (easting and northing). Then, it should test whether the user is within a box (430000, 80000) and (465000, 95000). If the input coor- dinate is outside this box, inform the user and quit the application. This is done because the elevation raster provided to you extends only from (425000, 75000) to (470000, 100000) and the input point must be at least 5km from the edge of this raster.
2.2 Task 2: Highest Point Identification
Identify the highest point within a 5km radius from the user location.
To successfully complete this task you could (1) use the window function in rasterio to limit the size of your elevation array. If you do not use this window you may experience memory issues; or, (2) use a rasterised 5km bu↵er to clip an elevation array. Other solutions are also accepted. Moreover, if you are not capable to solve this task you can select a random point within 5km of the user.
2.3 Task 3: Nearest Integrated Transport Network
Identify the nearest Integrated Transport Network (ITN) node to the user and the nearest ITN node to the highest point identified in the previous step. To successfully complete this task you could use r-trees.
2.4 Task 4: Shortest Path
Identify the shortest route using Naismith’s rule from the ITN node nearest to the user and the ITN node nearest to the highest point.
Naismith’s rule states that a reasonably fit person is capable of waking at Page 2 of 5

5km/hr and that an additional minute is added for every 10 meters of climb (i.e., ascent not descent).
To successfully complete this task you could calculate the weight iterating through each link segment. Moreover, if you are not capable to solve this task you could (1) approximate this algorithm by calculating the weight using only the start and end node elevation; (2) identify the shortest distance from the node nearest the user to the node nearest the highest point using only links in the ITN.
To test the Naismith’s rule, you can use (439619, 85800) as a starting point.
2.5 Task 5: Map Plotting
Plot a background map 10km x 10km of the surrounding area. You are free to use either a 1:50k Ordnance Survey raster (with internal color-map). Overlay a transparent elevation raster with a suitable color-map. Add the user’s starting point with a suitable marker, the highest point within a 5km bu↵er with a suitable marker, and the shortest route calculated with a suitable line. Also, you should add to your map, a color-bar showing the elevation range, a north arrow, a scale bar, and a legend.

5 Marking Scheme
The mark scheme is distributed in tasks as follows (total of 100):
Task Description
User Input.
Highest Point Identification.
Nearest Integrated Transport Network.
Shortest Path.
Map Plotting
Extend the Region.
Creativity marks are available under certain conditions for adding features that have not been specified.*
n.
1 16 2 16 3 16 4 16 5 16 6 10 7 10
Each completed task will be evaluated based on: the submitted project, the report, if regular commits on the GitHub repository have been made, if com- ments to your code are clear so that it can be understood by others, if PEP8 style is applied, if you incorporated some simple error handling functionality, if the work was properly distributed among the members of the group.
*The creativity marks will be considered only if you have scored more than zero on all the other tasks.
