Kontrólpunktar fyrir loftmyndatöku - Aerial Ground Control Points
[IS] Náttúrufræðistofnun heldur utan um kontrólpunkta sem er settir niður til að staðsetja loftmyndir. Í flestum tilfellum er um ræða hvíta ferningar sem eru 60x60 sm, en á jöklum eru þeir bleikir. Þar sem ekki er hægt að setja niður kontólpunkta í formi ferninga er miðað við aðra fasta punkta í landslaginu.
X, Y nákvæmni: 2-3 sm
Hæðarnákvæmni: 3-5 sm
Fitjueigindir, útskýringar:
efni_raun: Lýsir gerð punktsins (Náttúrulegur punktur, Gúmmímotta, Málað, Suðuplast, Bleik plata). Eiginleiki mynd sýnir hvað er mælt, almennt miðjan á hlutnum nema annað sé tekið fram á myndinni.
austur_maelt: Austur-hnit í ISN2016 EPSG:8088
nordur_maelt: Norður-hnit í ISN2016 EPSG:8088
ish_haed_maelt: ish2004 hæð
sporvolu_haed_maelt: Hæð yfir ellipsoíð
dagsetning_maelt: Mælingardagur
mynd: Hlekkur á mynd af punktinum (ef tiltækt)
maeli_adferd: Mæliaðferð, hvort sem er RTK eða FastStatic
[EN] This dataset contains ground control points placed by the Icelandic Institute for Nature Research that can be used for aerial imagery geolocation.
Normally white squares of 60x60cm or natural objects or pink squares 60x60cm on glaciers.
X, Y Precision: 2-3 cm
Elevation precision: 3-5 cm
Properties description:
efni_raun: describes the type of point (Natual point, Rubber mat, Painted, Welded plastic, Pink plate), the property mynd shows what is measured, generally the center of the object if not indicated differently in the image.
austur_maelt: easting in ISN2016 EPSG:8088
nordur_maelt: northing in ISN2016 EPSG:8088
ish_haed_maelt: ish2004 elevation
sporvolu_haed_maelt: ellipsoidal height
dagsetning_maelt: date of measurement
mynd: link to the image of the point (if available)
maeli_adferd: Measurement method if RTK or FastStatic
