Feature that calculates a multi-isochrone. The user should be able to chose an amenity or upload a spreadsheet with starting points.

• Basic SQL-function (pgdrivingdistance)
• Flexible SQL-function
• Allow scenario building
• Double check returning arguments
• Add Public Transport Stops
• Performance boost show network
• Limit number of starting points
• Add to front-end

• Calculate as multi-isochrone
• Improve show network function
• Boost nearest neighbour-function
• Final improvements
• Refactor other functions

Add a functionality in the front-end that clusters the POIs. POIs should be clustered at certain zoom levels.
The feature should not slow the application down and using it should be intuitive.

• Research on possible solution
• Cluster effect for all POIs in study_area (only shown at certain zoom level)
• Cluster effect for POIs intersecting the isochrone
• Interaction with POIs (see name, amenity, opening hours)
• Tested and Pushed

Example: https://openlayers.org/en/latest/examples/cluster.html

The application will be deployed on a VPS-server. At the moment the provider contabo is favoured.

• Get server
• Setup software
• Deployment Front-End/Parcel
• Auto backup functionality
• Auto update functionality
• Startup GOAT for the City of Munich

maybe we can find a housnumber which stands for the address. Otherwise we just take a dot.

I don't want to use something like Google Analystic. I am mainly interested in how many persons visit the site. It should not track the users.
There are open source solutions where we don't have to give the user data away.
We could use: Matomo

@majkshkurti

• Functionality front_end
• Geoserver
• Backend as JSONB

Write a script that regularly backups the database.

We have to document how the accessibility index and accordingly the heat-map is calculated.
It would be perfect to show the distance-decay function for several parameters. Once we have the heat-map feature improved we can work on this.

It would be good to change the color of the links that are modified and the new features. At the moment all of them are grey.

Make lines dashed as long as not added to the network in the backend.

This can wait for the next release

@majkshkurti

At the moment it should only be distinguished between bridge and way. After drawing the feature the use should be asked to set the attribute.

@majkshkurti

Create basic Website like the currenty Wordpress site. Focus is on an very basic general information about the project, how-to-use, link to the application and room for an extensive technical documentation.

• Get familiar with Jekyll
• Choose Theme and define Basic structure
• Create basic content
• Use README as first documentation
• Migrate Domain
• Push on Github
• Improve visual appearance (font-size, column width etc.)
• Develop methodology to create content
• Create Videos
• Create image opensource and OSM

Currently the routing network is not optimized neither for performance nor for accuracy. There are two main issues. If the links are very long the number of vertices is also very low, accordingly the accuracy can be affected.

Second especially at areas with a dense network it happens that the network is split into too many small pieces which affects performance significantly. Links that have identical attributes and are smaller than 10 meters accordingly can be merged.

• Split long links (first trial max. 500m)
• Merge unnecessary splited ways (max. 10 meters)
• Experiment with removing links for car only

Once the user clicks the button to draw an isochrone, the network disappears. The network however should stay on the map.

There is a new issue.

Allow to toogle the loaded network. All the network loaded by the user should be put into one layer and this layer should be controlled by a checkbox.

@majkshkurti

There is no legend shown when the scenario is calculated

@majkshkurti

The site is still listed as dangerous. Although the content was tested by google.

Set regular expression for all layers.

There are scripts existing that calculate the slope of the routing network. However the accuracy is not yet sufficient. The scripts has to be optimised for using 25x25m DEM.

Document for the website with the help of some images the methodological background of the isochrone calculation. Show how first how the driving distance is calculated and later on how this network is used to create the isochrone. Mention pros and cons of the provided functionality.

• Resize Popup window bridge/way
• Controls and Select Thematic data bold
• Stop Buttons resize when clicked
• Add different network type to legend (as HTML)
• Flip Checkbox network
• Test Tooltip
• Stop Network from disappearing when circle clicked again
• Stop circle when pressed ESC
• Ways loaded exclude class_id (501,502,503,504)
• Auto-refresh thematic data
• Change Name wp_style.css

@majkshkurti
If somehow we can do the Auto-refresh thematic data this would be great!

Network changes have to be enabled in order to perform scenarios after modelled network changes.

• Front-End
• NodeJS
• Good solution user management
• SQL-function
• Changes in Routing function
• Testing and bug fixes

The thematic data is not shown when double calculation is done

In the Thematic data control section they are written together without a space. The reason I wrote them together was that a function could not handle it with the space. So expect that the POIs are not selected when you simply add a space.
@majkshkurti

In order to consider opening times of the POIs, I want to pass an two additional parameters to the isochrone-function. The user should be able to pick a day and a time of the day. As result only POIs which are open at the time are shown.
@majkshkurti

• Test different impedance parameters
• Flexible calculation heatmap
• Integration front-end
• Test chart libraries front-end for different impedance functions
• Allow for dynamic recalculation

• add mouseover delete
• add mouseover modify
• add mouseover draw circle. Inform about max_size circle

@majkshkurti

Add some description to the download.

I could not unpack the downloaded data. Maybe there is an issue with the zipping.

@majkshkurti

This a new feature to improve GOAT.

• German Schools
• German Supermarket
• German/MVV Public Transport

• Remove islands
• Merge links
• Tune queries
• Research on further possibilities

At the moment the embeded videos are taking a lot of white space as sort of padding. This makes the site a bit ugly.
