CA Markov Method of Urban Growth using GIS Tutorial

CA Markov, People search lot of about CA Markov. But there is no proper GIS tutorial which Explain from Basic to run this model. If we know basic of GIS and data handling in Gis we will be easily able to run this Model. Its not a big deal. You just need ArcGIS and Terrset software to predict future land use and generate map for future. Think Few General points in Mind How it works. Lets think:
  1. New Urban area wll grow at boundary of older
  2. Some factor depends like distance between settelments
  3. Fistance from road
  4. Trend of change from Agriculture and forest each location
  5. Rate of Growth,
  6. Power of factor of change
And many More. You need only to model some layers and put in Machine learning model when the model trained put input to CA Markov model. This will predict future landuse map. If you found accuracy is not matching then Just change sampling rate and use hit and trail until it matches with actual land use if matched perfectly then Just o future and predict for year 205 and 2100.

ArcSWAT Tutorial

Landuse Tutorial

Sometime barren land has same appeared as urban area, Rivers are dry that appears as barren land. Even after final land use we think to add new class. But cannot add. Sometime forest in Hill shade area and appear black. Learn this all Everything how does with New Methods. More than Supervised classification and Get 90% Accuracy. Also learn how to do change detection. Like if urban area is increasing the how much area it takes from Agriculture or Forest, How Landuse is changing w.r.t Each class. Calculate are in Km, or Pixels. Lastly do accuracy report. Learn this everything. Only for LinkedIn offer who reading this post. This is already discounted link. Lear at your time. No time bound. Enrol now and watch more than 5 hrs step and your time.  You will also get valid certificate also.

ArcSWAT Tutorial

ArcSWAT is an watershed simulation model. Used for watershed, Water resource planning, Planning of Hydropower projects. It typical model to run with ArcGIS , Most of people facing error in SWAT Model. So, I have created a complete unofficial tutorial of SWAT model with ArcGIS. In this I covered Data download to final results. This include data preparation of SWAT model in Depth. Configuring swat model from scratch. I demonstrated using A live study area, from zero. I also covered custom data set for other countries to prepare for which no data is available, including preparation of soil maps. I covered to remove common error in weather data also. How to read output. How to manual configure inside SWAT model

landuse landcover classification step by step in GIS

This is first landuse landcover course on udemy the most demanding topic in GIS, In this course I covered from data download to final results. I used ERDAS, ArcGIS and ENVI. I explained all possible methods of land use classification. More then landuse Pre Procession of images are covered after dowanload and after classification, how to correct error pixels are also covered, So after learning here you no need to ask anyone about lanudse classification. I explained theoretical concept also during processing of data. I have covered supervised, unsupevised, combined method, pixel correction methods etc. For in depth of all methods enroll in this course. 

Problem faced During classification:
Some of us faced problem during classification as:

  1. Urban area and barren land has same signature
  2. Dry river reflect same signature as urban area and barren land
  3. if you try to correct urban and get error in barren
  4. In Hilly area you cannot classify forest which is in the hill shade area. 
How to get rid of this all problems Join this course in link below. Don't miss this chance its already at 70% off link for all visitor of this site

This will cost you only 1280 Rs/-

PC Configuration for Remote Sensing GIS - सुदूर संवेदन के लिए कंप्यूटर की कॉन्फ़िगरेशन

ये सारे तथ्य हमारे अपने अनुभव से हैं | अगर आप कोई कंप्यूटर लेने जा रहे हैं जिस पे GIS का काम हो तो एक बार निचे दी विडियो देख लें और यहाँ लिखा पड़ लें |

सॉफ्टवेर की साईट पे जो कंप्यूटर की कॉन्फ़िगरेशन दी होती है वो सिर्फ उस सॉफ्टवेर को इनस्टॉल करने के लिए दी होती हैं और ये लिखा होता है की ये कम ये कम इतना होना चाहिए | परन्तु जब आप उसे चलाते हैं तो उस से कहीं जयादा प्रोसेसिंग पॉवर की जरूरत पड़ती हैं |
GIS का काम करने के लिए हमारे अनुसार ये कॉन्फ़िगरेशन होनी चाहिए


  1. RAM 32 GB अथवा अधिक (DDR4 OR DDR5)
  2. इंटेल का xeon processor 4Ghz
  3. SSD (Non Rotating Hard disk) Solid State Drive

लैंडसैट 8 के डिजिटल नंबर को सतह के तापमान में बदलना

लैंडसैट 8 का प्रयोग करना 

ये जानकारी यहाँ भी उपलब्ध है (Source: https://landsat.usgs.gov/using-usgs-landsat-8-product)

लैंडसैट 8 में बैंड १० और ११ सतह का तापमान जानने के लिए प्रयोग  किये जाते हैं | जिसमे बैंड १० ताप तरंगो के कुछ पास के तरंग लम्बाई में है परन्तु बैंड ११ पूर्ण रूप से ताप को सेन्स करता है इस लिए बैंड ११ का प्रयोग करना की उचित समझा जाता है | परन्तु जब सॅटॅलाइट फोटो लेता है जो अदृश्य सूक्ष्म तरंग क्षेत्र  की हो वो  उसकी डिजिटल फिल्म में सीधे तरंग के (wavelength) तरंग लम्बाई के रूप में अंकित नहीं होती | क्योंकि डिजिटल फिल्म सिर्फ पूर्ण संख ही रिकॉर्ड कर सकती है दशमलव में नहीं , इस समस्या को हल करने के लिए उसे 16 बिट पे अंकित किया जाता है जिस से सब डाटा कुछ अधिक स्केल में अंकित होता है परन्तु सब रिकॉर्ड हो जाता है | इस अधिक डाटा को हम बाद में कम स्केल फैक्टर से प्रोसेस का के हम उसके मूल रूप में ला सकते हैं अथवा पूर्ण रूप से उस से वो प् सकते हैं जी के लिए वो बना है | परन्तु इस के लिए हमे डाटा को प्रोसेस करना होगा और गणित के मॉडल के द्वारा कैलकुलेशन (गणन्ना ) करनी होगी | इस तरह हमे सतह का तापमान मिल जायेगा | नासा हमे डाटा देता हैं परन्तु प्रोसेस उसे हमे करना होता है |  निचे वो सम्पूर्ण फार्मूला दिया है जिसके माध्यम से आप सतह का तापमान निकल सकते हैं | सतह का तापमान फसल , शहर की योजना और वाष्पीकरण की जानकारी के लिए महतवपूर्ण रहता है | ये सब की भी आप गन्ना कर सकते हैं | ये सारा कार्य आप एक एक से अधिक सॉफ्टवेर में कर सकते हैं परन्तु इस सब के लिए आपके कंप्यूटर की 8 GB, RAM हो i5 अथवा i7 प्रोसस्सेर हो और SSD हो तो अति उतम है , नहीं तो कंप्यूटर कुछ समय के लिए गरम हो जायेगा क्योंकि उसको कई अर्ब पिक्स्ले को प्रोसेस करना है | समस्त कार्य का फार्मूला निचे दिया गया है अथवा आप इस किताब को डाउनलोड कर के भी पड़ सकते हैं |


Conversion to TOA Radiance
OLI and TIRS band data can be converted to TOA spectral radiance using the radiance rescaling factors provided in the metadata file:
Lλ = MLQcal + AL 
where:              
Lλ          = TOA spectral radiance (Watts/( m2 * srad * μm))
ML         = Band-specific multiplicative rescaling factor from the metadata (RADIANCE_MULT_BAND_x, where x is the band number)
AL          = Band-specific additive rescaling factor from the metadata (RADIANCE_ADD_BAND_x, where x is the band number)
Qcal        = Quantized and calibrated standard product pixel values (DN)         

Conversion to TOA Reflectance
OLI band data can also be converted to TOA planetary reflectance using reflectance rescaling coefficients provided in the product metadata file (MTL file).  The following equation is used to convert DN values to TOA reflectance for OLI data as follows:
ρλ' = MρQcal + Aρ 
where:              
ρλ'          = TOA planetary reflectance, without correction for solar angle.  Note that ρλ' does not contain a correction for the sun angle.
Mρ         = Band-specific multiplicative rescaling factor from the metadata (REFLECTANCE_MULT_BAND_x, where x is the band number)
Aρ          = Band-specific additive rescaling factor from the metadata (REFLECTANCE_ADD_BAND_x, where x is the band number)
Qcal        = Quantized and calibrated standard product pixel values (DN)

TOA reflectance with a correction for the sun angle is then:
ρλ ρλ'=ρλ'
cos(θSZ)sin(θSE)
where:              
ρλ          = TOA planetary reflectance
θSE         = Local sun elevation angle. The scene center sun elevation angle in degrees is provided in the metadata (SUN_ELEVATION).
θSZ         = Local solar zenith angle;  θSZ = 90° - θSE
For more accurate reflectance calculations, per pixel solar angles could be used instead of the scene center solar angle, but per pixel solar zenith angles are not currently provided with the Landsat 8 products.

Conversion to At-Satellite Brightness Temperature
TIRS band data can be converted from spectral radiance to brightness temperature using the thermal constants provided in the metadata file:
T = K2
ln( K1 +1)
Lλ
where:              
T           = At-satellite brightness temperature (K)
Lλ          = TOA spectral radiance (Watts/( m2 * srad * μm))
K1          = Band-specific thermal conversion constant from the metadata (K1_CONSTANT_BAND_x, where x is the thermal band number)
K2          = Band-specific thermal conversion constant from the metadata (K2_CONSTANT_BAND_x, where x is the thermal band number)

एक अनोखा गाँव जो पुरातन ज्वालामुखी पे बसा है

भारत में भुमते हुए एक दिन ऐसा गाँव मिल गया जो पुरातन ज्वालामुखी के लावा पे बसा है | वो भी इतना पुराना जब धरती अन रही थी अथवा हिमालय बन रहा था | क्योंकि वर्तमान समय में ये सक्रिय नहीं है | ये इतना पुराना प्रमाण है की हमे धरती और इसके जियोलाजिकल इतिहास के बारे में काफी कुछ बता सकता है | वर्तमान में ठीक इसके उपर लावा प्रवाह के क्षेत्र में गाव बसा हुआ है | शायद गावं के लोग भी इसे नहीं जानते की वो किस पे बसे हैं | देखें निचे दिया गया पूरा विडियो |

PC Requirement for GIS Software

If you visit ESRI Website for PC Configuration for GIS, you Get much lower requirements. But actually thet are written as "minimum to run" Means that only to run software not to process. For processing large data you need High End PC, otherwise your processor burn for long term use and procession of GIS software. Normally if your image is more than 4GB it take large amount of time to process, you cannot process whole state or country. If command given it take couple of hours or end with insufficient memory error. So here is PC Requirement if you are going to Build desktop or thinking about laptop. Model or made of pc does not matter, its configuration just matter. 

Best PC Requirement for GIS Software.

Sr.No
Component
Specification
Remarks
1
Processor
i7 or whichever Higher while you reading it
Recommended more then 3.0Ghz
2
HDD or SSD
HDD is not recommended for large process environment.
Use SSD instead of HDD
Because SSD has no moving part and having write speed of 1TB/s and HDD has just 30mb/s
