Data Upload Functionalities

Introduction

The platform allows you to upload custom data from your computer to your Hotmaps user account. This part is closely linked to the export function as the final goal of those two functions is to export data, edit it and visualize it on the toolbox later by importing those data back. Please note that your uploaded data can be visualized and certain number of them can be used in the calculation modules.

This operation requires a user account. The registration and login processes are explained on the User account page.

Uploaded data should respect the data formats and projection defined by the toolbox. To assure that you are uploading right data set, you can always download a sample data from the toolbox for a small area and subsequently, update and fill it with your own data. In case of CSV files, makes sure that you keep all the columns, column separator, and data types as of the downloaded sample. We suggest to open CSV files in text editor rather than MS Excel in order to see all characters inside it. Regarding the upload of raster files, following aspects should be considered:

The raster should have the coordinate reference system of ETRS89-extended / LAEA Europe - EPSG:3035;
The coordinate of the raster origin (top-left corner of the raster) should be a multiplicand of 100, e.g. (4334900, 3019700);
The resolution of the raster map should be 100x100m;
The raster should refer to a location in Europe.
pay attention to the units of the original data set shown on the toolbox. For example, the heat density map has the unit of MWh/ha and if your uploaded layer has another unit, you may encounter with difficulty in visualizing your data. Furthermore, you will not get a correct answer from the calculation modules.

The citiwatts toolbox is a living platform: As the research project as well as its sister and follow-up projects evolve, (new) functionalities are refined and bugs are addressed and solved. The toolbox is hosted in two environments: the development server and the production server. The development server has the most up-to-date version, with most of issues and bugs solved, but it might be unstable as developers keep working on it daily. The production server instead is a stable environment.
