# 90. الاستعلام: جلب بيانات SatelliteImagery حسب الهندسة استرجاع إحصاءات مؤشر الغطاء النباتي لأي شكل هندسي مخصص - **لا يلزم وجود حد حقل مسجل**. يقوم هذا الطرف النهائي بحساب إحصاءات الملخص للبكسلات داخل الشكل الهندسي الخاص بك بينما **تجاهل البكسلات المغيمة**. مدعوم حاليًا على **سينتينل-2 (S2)** , **لاندسات (L4/L5/L7/L8/L9)** و **بلانيت (PS)** مزودين. {% hint style="danger" %} تتبع هذه الصفحة أنماط واجهة برمجة تطبيقات GeoPard و [المصادقة](https://docs.geopard.tech/geopard-tutorials/api-docs/authorization-apikey-credentials-or-oauth-2.0) المستخدمة عبر نقاط نهاية GraphQL. {% endhint %} ## ما يمكنك فعله * استعلام **مؤشرات الغطاء النباتي** لـ **نقاط، متعدد النقاط، مضلع، ومتعدد المضلعات** الأشكال الهندسية. * اختر صورًا/تصويرًا **المزودين**: `S2`, `L4`, `L5`, `L7`, `L8`, `L9`, `PS`. * احصل على **نتائج موسومة بالتاريخ** لكل اكتساب مع: * `خالية من السحب` - نسبة الشكل الهندسي الخاص بك الخالية من السحب، نطاق القيم من 0 إلى 1، حيث 1 يعني خالية تمامًا من السحب. * `value` - إحصاءات للمؤشر المحدد محسوبة **فقط** على البكسلات الخالية من السحب، يتضمن `min`, `max`, `avg`, `mdn`, `var`, `std`. * اختياريًا قدّم **نطاقات** مصفوفة من نطاقات قيم المؤشر لحساب إحصاءات التغطية. عند التقديم، سيتضمن الرد حقلًا `نطاقات` يبين النسبة المئوية للمساحة التي تقع ضمن كل نطاق محدد. * **المساحة المحتلة بكل لون/نطاق** - استنادًا إلى قيمة المؤشر (من منخفض إلى مرتفع) * **نسبة التغطية** - قيمة من 0..1 لكل نطاق تمثل نسبة السطح ## المؤشرات المدعومة `EVI2`, `NDVI`, `RVI`, `LAI`, `OSAVI`, `SAVI`, `GNDVI`, `IPVI`, `GCI`, `WDRVI`, `RCI`, `SBI`, `MCARI1`. تتبع تعريفات المؤشرات كتالوج مؤشرات الغطاء النباتي الخاص بـ GeoPard [كتالوج مؤشرات الغطاء النباتي](https://docs.geopard.tech/geopard-tutorials/product-tour-web-app/satellite-monitoring/indices-for-crops-and-soils#vegetation-indices) المستخدم في جميع أنحاء واجهة برمجة التطبيقات. ### معاملات الإدخال

المؤشرقيمة تعداد (انظر أعلاه)✅مؤشر الغطاء النباتي الذي سيتم حسابه.
المزودين[مزود!]!✅أي من S2, L4, L5, L7, L8, L9, PS.
startDateسلسلة نصية (ISO8601)✅بداية شاملة، على سبيل المثال "2025-05-10T00:00:00.000Z".

geojsonسلسلة نصية✅A GeoJSON محول إلى نص من النوع نقطة / متعدد النقاط / مضلع / MultiPolygon (WGS84 [خط طول، خط عرض]). تذكر هروب علامات الاقتباس داخل السلسلة.
نطاقات[[Float!]!]❌مصفوفة من [min, max] أزواج من نطاقات قيم المؤشر لحساب إحصاءات التغطية
## **إرشادات الأداء** * بالنسبة للأشكال الهندسية من نوع مضلع/متعدد المضلعات، احتفظ بنطاقات التواريخ ضيقة (**\~10–15 يومًا**) بسبب وقت المعالجة. * **مهلة:** 30 ثانية. استخدم أيامًا أقل و/أو مزودين أقل إذا وصلت إلى الحد. * بالنسبة للنقطة/متعدد النقاط، النطاقات الأكبر عادةً ما تكون مقبولة (النقاط خفيفة الوزن). ## شكل الاستجابة ```graphql graphqlنسختحرير{ geojson # صدى للشكل الهندسي الذي أدخلته (محول

additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.geopard.tech/geopard-tutorials/ar/mstndat-wajhh-brmjh-alttbyqat/nzrh-aamh-ala-tlbat-wajhh-brmjh-ttbyqat-geopard/90.-alastalam-jlb-byanat-satelliteimagery-hsb-alhndsh.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
