It would be good if we could have default styles linked to the category returned. At the moment these are:-

'General','Events','Community','Planning', 'Democracy', 'Education', 'Health', 'Highways and Transport','Waste and Recycling', 'Environment', 'Crime'

An item can have more than one category so the first in the list would be used

The plugin will be written in python and be targeted at QGIS 3 API.

It will be available from the plugin drop down menu and an icon on the QGIS menu bar

The plugin will present two screens to the user:-

• settings
• search

The setting screen will allow the user to change the base URL for the search. This will default to:-

https://api.sh.vialocus.co.uk/

The search screen will allow the user to do the following:-

1. set the endpoint. These will be retrieved from endpoints.json

{
 "category_search" :  "/search/{Category}/{Search Text}",
 "bounding_box" : "/bboxsearch/{**BBOX**}/{Category}/{Search Text}",
 "reference_search" : "/refsearch/{Reference}/{Category}",
 "point_search" : "/pointsearch/{**LOCATION**}/{Distance}"
}

Items such as {Category}, {Search text} are variable supplied by the end user and must be used to create a search form. Variables are not mandatory.

Items such as {BBOX} and {LOCATION} are filled by the system

• BBOX is the current canvas extent in lat/lon (WGS84) format as follows:-

xmax ymax, xmin ymin

eg:-

-0.8 51.3,-0.7 51.4

• LOCATION is the centre of the current canvas in EWKT format

eg:-

SRID=4326;POINT(-1.1 53)

2. carry out the search and display the results on a temporary layer. If the layer does not exist it will be created, if it does exist then the items will be added to it.

The API returns results in GeoJSON format.

3. If time permits categories should be a drop down with the valid items retrieved by the following call:-

<URL>/list_categories
eg:-

https://api.sh.vialocus.co.uk/list_categories

https://github.com/wonder-sk/qgis-minimal-plugin

These need adding (and testing)

/search/{category}/{search_text}/{limit}/{offset}

/pointsearch/{location}/{location_distance}/{category}/{search_text}/{limit}/{offset}
(location is in EWKT format, distance in metres)

/refsearch/{reference}/{category}/{limit}/{offset}
(reference alphanumeric)

/address_search/{address}/{limit}/{offset}
(address is a freeform addresss

limit default 100, offset default 0
