I am building wayfinding interactive map for a building with an animated path (a direction arrow from point A to Point B). I have tried and found that Mapplic Plugin for Wordpress is suitable for this job. See https://mapplic.com/routes . However, you can propose other solutions also but i am looking something similar to Mapplic with customization. I don't expect a custom programming because that will be time-consuming and not open for further improvement.
I expect some customization :
1. Offline support. All link and pages can be access even without internet. Once downloaded early in the morning or last downloaded page, it will never show "page not found". It will try to get the latest map in the background. This is a kiosk mode.
2. Make a simple interface for end user to add/edit/delete new landmarks in the main menu. (at the moment from Mapplic, user need to go to Mapplic Plugin and the interface and listing is not strait forward. A better UI overall.
3. At the moment, we require usage of external program such as Illustrator for marking landmark SVG ID, so it's troublesome. If there's a web-based, on the fly for SVG ID marking (active hotspot referral to click). I know other software that does this, but not using SVG, but PNG also possible. The objective is to touch on the map and popup the location info/image.
4. Mapplic Route (additional plugin) is available for for animated path, One additional layer is required, composed of connected lines along the walkable paths and location entrances. I did not purchase this yet, but once final i will purchase it and explore. I never install it either.
5. Other customization such as overlay location like amenities such as Toilet, ATM machine, Parking. Mapplic already has this overlay features, but if you willing to take the project I will be glad to work with you. including graphic and user interface.
6. Mapplic support CVS upload for bulk entry. But I need guidelines and programming customization, all data entry and drawing/graphics can be done by my team.
I have installed and try Mapplic demo here http://wayfinding.israk.my/mall/ the backend also attached. Mapplic docs is here https://mapplic.com/docs/
