KML standard oficial OGC

Vasile Crăciunescu
Administrator
De astazi, 14 Aprilie, formatul KML (Keyhole Markup Language) a devenit
standard deschis OGC (Open Geospatial Consortium). KML a fost dezvoltat
initial pentru a permite integrarea datelor geospatiale in Google Earth.
Intre timp, datorita design-ului simplu si a flexibilitatii deosebite,
formatul a fost adoptat de tot mai multe aplicatii si servicii web ca
standard  "de facto" pentru publicarea on-line a informatiilor cu
caracter geospatial. In perioada urmatoare, Google va renunta complet la
controlul KML, transferind catre OGC responsabilitatea dezvoltarii
viitoare a formatului. Intreaga procedura este estimata sa dureze
aproximativ un an. Pentru mai multe detalii va recomad urmatoarele resurse:

Apropos de KML, exista si un plugin pt. ArcGIS care permite exportul datelor in acest format, insa e doar o versiune trial, de 14 zile. Oare il vor face open-source?

Re[2]: KML standard oficial OGC

Vasile Crăciunescu
Administrator
Mihai,

Ma indoiesc ca plugin-ul respectiv va fi facut open source. Pe de alta parte exista numeroase tool-uri free sau open source care pot transforma un fisier ESRI Shapefile in KML. Gasesti mai jos doar citeva exemple:

http://gdal.org/ogr/
http://shp2kml.sourceforge.net/
http://www.zonums.com/shp2kml.html


Numai bine,
Vasile

Salutare,

Este deja opensource si nu cu putin efort ;-)

Restul ? E la latitudinea si decizia ESRI ce vor
ei sa includa si ce nu vor, third party-urile vor
profita binenteles pentru cate un plugin platit.

http://www.gdal.org/ogr/ogr_formats.html
http://www.gdal.org/ogr/drv_kml.html

  O sa vedeti in 2-lea link ca formatul KML are
totusi cateva limitari daca il utilizati in tandem
cu GoogleEarth, aceste limitari sunt din cauza
GoogleEarth si  nu provin din specificatiile KMZ.

  Gdal v1.5 stie deja  KML/KMZ in mod R/*W cu
toate facilitatile oferite de acesta, mai putin incapsulare
rasteri din cate m-am jucat si cateva detalii marunte,
pur si simplu KML e mult mai flexibil decat orice format
cunoscut pana acum, va trebui updatat serios gdal pentru
a profita pe din plin de acestea, in schimb nu se va putea
exporta dupa aceea ceva din KMZ in e.g .shp cel putin
nu 1:1. E.g se pot incapsula transparente, iconite culori
si alte minuni la reprezentarea setului. E un lucru nou la
capitolul set de vectori si destul de complicat de implementat
cu toate feautures-urile oferite, e putin cam iesit din tipare
pentru moment, mai trebuie timp sa se inglobeze toate
feautures-urile.

  Cum engine-ul de baza de la ArcGIS >9.2 in sus e chiar
gdal (v1.4) nu e exclus ca odata cu ArcGIS 9.3/10 sa
fie livrat cu o librarie gdal mai actuala (v1.5) implicit care
va sti KMZ, asta daca isi doreste si ESRi realmente sa mearga
pe acesta linie ca si pana acum, ii putem intreba la ei pe forum.

   Pe undeva inteleg intentia de a nu se arunca la ultima versiune
din partea ESRI sunt convins ca pana cand trece ciclul lor
de release ~2ani nu vor include ultima versiune de gdal asa
repede, plus versiunea 1.5 nu e chiar cea mai stabila in momentul
de fata.

     Pe de alta parte, GlobalMapper stie KML/Z fara nici o
problema si o face bine de tot, iar daca deranjeaza ca e
produs comercial se poate apela la gdal (implictit front-enduri
 q-gis, grass ultimele versiuni) nu stiu daca mai exista si alte tooluri
dar sunt convins ca daca da nu e neaparat cea mai meticuloasa
implementare conform speciificatiilor recent aprobate si de OGC.


Viata lunga pentru KML !
