Maps online + shapes + my data ?

RadekHavelka

Hello,
  I apologise, if you find my questions a bit crazy, but I discovered this site yesterday and I'm totaly lost in all the terms and amazing possibilities ArcGIS offers, trying to find the way it will work for my project.

  In short - we create and host for free a database of military units, from any period of human history (of course, mainly from 20-21th century). There is nothing similar to our project, because we store the data in kind of semantic web, with defined relationships between objects, so we are able to produce some interesting overviews and automated reports, order of battle for given date and so on. The main goal is to store any data in specified and described form, so they can be reused later, and we don't have to do the things manually again (currently we list several thousand units and this database is growing every day, imagine that for each unit we keep the information about its subordinate units, its superior unit, its commanders, its dislocation, even weaponry, logos and patches, medals and citations ... its huge amount of data). For example, someone is interested in history of a unit, someone else wants to see a battlefield, where this unit participated. Someone else is interested to see a career of a commander ... many different views, that can be satisfied using good data structure 🙂

  Part of our project is "geolocating" the unit during its existence. Simplified, we pinpoint them on the map, while setting a DATE and TIME, when this unit has been on given spot on the map. Again, this can be used for several automated "reports", like "show me way of 1st Infantry Division Big Red 1 during WW2 thru Europe". There are several dozens of users, who are (or will be) doing this, so it needs to be done over the internet browser (preferable Firefox or Chrome, but cannot exclude IE as some users are using it ).

  So far, I'm able to program this using google maps, jQuery and our PHP backend, because the units are simple POINTS on the map (using own set of military marking icons to differentiate between infantry, armoured, cavalry, .... divisions, corps, brigades ... you get the idea I guess).

  But, when showing the movements, and by trying to reproduce maps like this



  I need the possibility to draw lines and arrows, and this is why I came to this site. I've found this

http://www.arcgis.com/home/webmap/viewer.html

  and was amazed by the possibility to DRAW, MODIFY and ROTATE the arrows, change their COLOR and also that they SCALE with the map ! This is something I'm really looking for. I'm a programmer, can do PHP and able to work with JS, but this type of modification of shapes is far beyond my skill (and why to do it, when someone already did it )

  Now, my question is - is this something I can add to my maps, via some JS library or something, or is it bound to this server only ? Because, for us, we need to store data locally on our server (no offense, but sites quite often get shut down, change their URLs and so on, so we are not going to risk, that after adding several hundert thousand locations and relationships to our object these maps will get lost somewhere), at least the relationship - ID of the UNIT, DATE, COORDINATES, plus these new objects - ARROWS and LINES, their COORDINATES and SHAPE, DATE and ZOOM LEVEL. And we need to be able to draw it back to a map as an "overlay", but "user controlled", meaning the user can pick a DATE, TIME, and move freely on the map to see the location of the units (all over the globe and his chosen zoom level). For now, this is done via generated georss feed added to google map.

  So, please, help me answer this question, or tell me which product am I exactly looking for , and of course if there is free solution or something we need to buy.

  Thank you
