"Accuracy can be defined as the degree or closeness to which the "
"information on a map matches the values in the real world. Therefore, "
"when we refer to accuracy, we are talking about quality of data and about"
" number of errors contained in a certain dataset (Pascual 2011)."

"Local or relative accuracy can be defined as the degree to which de "
"distances between two points on a map correspond to the actually "
"distances between those points in the real world."
msgstr ""

#: ../../map-accuracy.rst:12
msgid ""
"Relative accuracy is independent of the location of the map in the world,"
" so a map can have a high relative accuracy (in size and shape) but its "
"position in the world can be shifted (Figure 1)."

"Absolute accuracy is the accuracy of the reconstruction in relation to "

#: ../../map-accuracy.rst:35
msgid ""
"Each project has specific accuracy needs to be met. For instance "
"assessing the progress in a construction site or measuring an area "
"affected by a fire does not require the use of GCP, since absolute "
"accuracy will not impact the decision making process. In the other hand, "
"there are tasks on which accuracy is critical, for example project "
"compliance evaluations and land title surveying, which require a higher "
"relative and absolute accuracy."

msgid "What to expect"
msgstr ""

#: ../../map-accuracy.rst:41
msgid ""
"In general terms, one can expect the relative accuracy to be in the order"
" of 1 to 3 times the average GSD for the dataset. And as for the absolute"
" accuracy, one must consider that it is dependent of the GPS unit mounted"
" in the UAV but the horizontal accuracy of a standard GPS is usually in "
"the range of 2 to 6 meters and the vertical accuracy between 3 to 4 times"
" the horizontal accuracy."
msgstr ""

#: ../../map-accuracy.rst:43
msgid ""
"When using GCP, absolute accuracy can be improved to 2.5 times GSD for "
"the horizontal accuracy and 4 times the GSD for the vertical accuracy "
"(Madawalagama 2016)."
msgstr ""

#: ../../map-accuracy.rst:45
msgid ""
"At a GSD of 1cm, the accuracy is to that of the RTK GNSS, and is within "
"1:200 scales according to NSDI & FGDC mapping accuracy standards during "
"sub-optimal conditions (Barry 2013)."

msgid "**Weather**"
msgstr ""

#: ../../map-accuracy.rst:53
msgid ""
"Weather conditions have direct impact in the photogrammetry results, so "
"it is important to consider cloud coverage, wind speed, humidity, sun’s "
"altitude and other factors influencing the UAV stability and terrain "
"illumination."

msgid "**Cameras**"
msgstr ""

#: ../../map-accuracy.rst:57
msgid ""
"Bigger and better sensors produce less noise and more clearly focused "
"images. Also consider that rolling shutter cameras produce distorted "
"images when the UAV is moving, so global or mechanical shutter cameras "
"are advised for mapping jobs."
msgstr ""

#: ../../map-accuracy.rst:60
msgid "**Flight altitude**"
msgstr ""

#: ../../map-accuracy.rst:62
msgid ""
"The higher the flight altitude, the larger the image footprint and GSD. "
"The resulting larger GSD the accuracy will be decreased as there will be "
"less detail in the recognizable features. When a smaller GSD is required "
"an altitude of 3 to 4 times the height of the highest point is "
"recommended."

#: ../../map-accuracy.rst:65
msgid "**Flight speed**"
msgstr ""

#: ../../map-accuracy.rst:67
msgid ""
"Flight speed have special effect in cameras equipped with rolling "
"shutter, while those equipped with global or mechanical shutter tends to "
"reduce this effect. UAV equipped with RTK positioning systems are also "
"affected with the speed, but with hover at each photo taken, you can get "
"very good accuracy. If instead you are moving during each photo take, the"
" accuracy is going to be limited by two factors: the speed at which you "
"are moving multiplied by the 1 second increments of RTK (Mather 2020)."
