summary

The motivation of this program is to help answering questions such as:

This repository contains code to produce two related programs:

Both programs use the Qt framework, C++ and QML languages, and can be built (using a suitable modern compiler) for the most common targets: Windows, macOS, Linux and Android operating systems.

Upon startup, this program shows a map of Barcelona, centered at the default location point: Glòries square, a blue circle labeled as "Current Location", and the trees found nearby. The user can change the location by hand, with a long press and hold of the main mouse button or touch screen, or automatically using the device’s GPS (menu option "Update Position". The user can change the zoom scale either with the mouse wheel or using a "pinch" gesture in the touch screen.

Over the map, each tree is represented as a green circle. When using the maximum zoom and hovering the mouse pointer over each circle the program pops a label with the scientific name. Clicking with the mouse main button, or touching on a touch screen, the program pops a dialog with detailed information about the specimen, including a link to a Wiki page for extended information about the species, and a link to the street view of the address.

Searching functions. The user may search the trees that will be represented in the map, using the following criteria.

In addition to the map representation, the list of trees found by any of the search functions can also be seen as a list (menu option "View Results List"). Each element of the list contains a correlative number, the scientific and common names, the address and the distance to the current location. Pressing with the mouse or touching the screen on one element of the list, that element is selected and highlighted, and also labeled on the map that will be centered on the selected tree.

Configuration settings. The user may change some visualization options using the menu option: "Settings".

The first inspiration to make this program was the work of Juanjo Vidal Arbrat viari de la ciutat de Barcelona using one the datasets from Open Data BCN.
