Sequence the steps for georeferencing a map in QGIS:

(A) Select transformation type
(B) Open the image to be georeferenced
(C) Open the map that you want to georeference
(D) Find ground control points (GCPs)

Choose the correct answer from the options given below:
1. (A), (B), (C), (D)
2. (A), (C), (B), (D)
3. (B), (A), (D), (C)
4. (C), (B), (D), (A)

QGIS में किसी मानचित्र को जियोरेफरेंस (georeferencing) करने के चरणों को सही क्रम में व्यवस्थित कीजिए:

(A) रूपांतरण प्रकार (transformation type) का चयन करना
(B) जियोरेफरेंस की जाने वाली छवि को खोलना
(C) जिस मानचित्र को आप जियोरेफरेंस करना चाहते हैं उसे खोलना
(D) ग्राउंड कंट्रोल पॉइंट्स (GCPs) खोजना

नीचे दिए गए विकल्पों में से सही उत्तर का चयन कीजिए:
1. (A), (B), (C), (D)
2. (A), (C), (B), (D)
3. (B), (A), (D), (C)
4. (C), (B), (D), (A)

EXPLANATION Remote Sensing, GIS, GPS, Digital Soil Mapping and Precision Agriculture

The logical sequence for performing georeferencing in QGIS:

  • Open the base reference map / layer in QGIS Canvas.
  • Open the unreferenced raster image inside the Georeferencer tool.
  • Identify and place Ground Control Points (GCPs) linking image coordinates with map coordinates.
  • Configure Transformation settings (Polynomial, Thin Plate Spline, resampling method, target CRS) and execute.
Therefore, the correct sequence is (C), (B), (D), (A).

QGIS में जियोरेफरेंसिंग की सही चरणबद्ध प्रक्रिया:

  • QGIS में संदर्भ बेस मैप खोलना।
  • जियोरेफरेंसर टूल में उस छवि/रास्टर को खोलना जिसे जियोरेफरेंस करना है।
  • ग्राउंड कंट्रोल पॉइंट्स (GCPs) को पहचानना और जोड़ना।
  • रूपांतरण सेटिंग्स (transformation type) का चयन करना और प्रक्रिया चलाना।
अतः सही क्रम (C), (B), (D), (A) है।
