ABSTRACT:
Here results of reseaches and experiments carried out at TsNIIGAiK in 1992-1994 with participation of field
expedition for timely revision of plans and maps of scales 1:500-1:10 000 then using an Engined delta-glider
(Motodeltaplan-MDP) are presented. Two technology variants were tested: one-using photographic materials
obtained from MDP aerial survey with the futher airvisual observation from the MDP and the other one -by
using in flight and on-ground interpretation data with no additional aerial surveys.
1.INTRODUCTION.
TsNIIGAIK has prepared technology of timely
revision of large-scale (1:500 - 1:10 000)
topographic plans and maps using engined delta-
glider (micro-light aircraft), in Russian:
MOTODELTAPLAN -MDP.
Choice of MDP for these works was based on
achieving of effectivity because of lower (for the
order) cost of exploitation, comparing it with
traditional carriers such as An-30,
Mi-4; possibility of approaching of a basings place of
air-survey party to work-object; simplicity of
exploitation and technical serving, absence of hard
demands of choice of take off and landing field - its
Size and coverage; low speed of flying (60 km/h),
letting look at changes of areas more thoroughly, big
viewing, possibility of virage flying round the objects.
Two variants of technology were used by materials
of new air survey by MDP with folow airvisual
inspections on it and with materials of interpretation
flight and landings without doing new airsurvey (laing
some airsurvey of strips in special necessity).
Experimental laboratory works consisted of
foundation of a programe and a working project of
experimental works, preparation of working map
manuscript of revision,definition of degree of
modernity of a plan and map and a control of their
accuracy; definition of air images conteining of
photokeys of update, keeping duty map with an
information of videofilm and other cartographic
originals; laboratory preparation of air images and
321
fotogrammetric bridging of net; making of originals of
changes with MDP images on AP "Stereoanagraph-
2". getting of up-date originals.
Experimental field works were done in a region of a
small town and connected collection of materials of
the cartographic meaning in various organizations;
spade-work of parts of area for survey from MDP:
airsurvey; training and reconnassance flights on
MDP in altitude 100-250m and survey of an
videofilm, recognizing and interpretation flights on an
altitude of 150m for discovery of changes and
conteining for plans 1:500 and 1:2000 and a map of
scale 1:10 000; interpretation flights for revision of
plans of scales 1:500 and 1:2000 with landings for
correcting of map 1:10 000, control field observation.
A programe of experimental works defined
sequence, volumes and time of realization of spade-
work and afterflying field works.
2. EXPERIMENTAL WORK.
2.1 Terrain areas observed.
For experiments three parts were chosen. First one
was correspondid to a list of map of scale1:10 000.
Hilled (excess over midd flatness +54m) settlement
With separate forest massives and country-sides.
Square is 16sq.km. Degree of modernity of map is
(are) 64%. The second one is equal to plan 1:2000.
Square is 1.0sq.km. On a plan a settlement of town
kind (buildings from 2 till 9 floors) with developed
communication net. Excesses over medium flatness
are + 22m. Degree of modernity of plan is 46%. The
third one is equal to three plans with a scale 1:500
of common square 0.3sq.km. It situated on area of
