algorithm - How to represent street address ranges for geo location lookups? -

-

i have following type of inputs:

zone 1 =>   alabama street, 1 135, west side   alabama street, 2 144, east side   bahama square, 2 4 zone 2 =>   bahama square, 5 8   cecil street, 3 27

etc.

these data represent zones within area. small disctrict in city, defined couple of enclosing streets.

if i'm given geo location (latitude, longitude), how can map value zone in above context? it's obvious google maps lookup give me address, how proceed there? best way represent kind of data (address ranges) effective zone establishment?

(whoa, 3 questions within 1)

i'll take stab @ followup question. assuming streets 1 .. 6 in zone 1 major streets , zeta side street between these streets within address range.

my solution form shapefile zone , check if lat/lng of address check within shapefile. here's approach detail:

  1. use reverse api lat/lng of each street endpoint (e.g., 1 w. alabama, 135 w. alabama, etc).

  2. use these endpoints create polygon shape (shapefile) around zone.

  3. use reverse api lat/lng of address check.

  4. check if lat/lng within polygon shape.

if decide though use matching address, here's link postal standard addresses. can use standard normalizing addresses.

c# - How to set Z index when using WPF DrawingContext? -

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

visual c++ - Using relative values in array sorting ( asm ) -

i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values? (the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
