मैं जनगणना के आकार-प्रकार (बहुभुज) के साथ काम कर रहा हूं और मेरे पास अंक के साथ एक और तालिका है। हम रिकॉर्ड करते हैं कि कौन सी जनगणना प्रत्येक बिंदु को रोकती है। मेरे पास एक बिंदु है जो सभी ST_Within और ST_Touches प्रश्नों के लिए गलत है। हालाँकि, यह एक ब्लॉक पर ST_Intersects के लिए सही है।
यदि यह एक और बहुभुज होता तो मैं समझ सकता हूं कि यह कैसे होगा लेकिन एक बिंदु (मैंने सत्यापित किया है कि यह मामला है) अंतर के लिए सही हो सकता है लेकिन भीतर और छू दोनों के लिए गलत है? QGis में इसकी जाँच करने पर ऐसा प्रतीत होता है कि इसे टच के लिए सही होना चाहिए।
हमारी तालिका में लाखों अंक हैं और केवल इस एकल बिंदु के पास कोई मुद्दा है। मैंने बहुभुज और बिंदु दोनों पर ST_IsValid चलाया है।
मैं ज्यामिति डेटा के लिए काफी नया हूं। क्या मुझे कुछ याद आ रहा है कि यह कैसे काम करता है?

संभवतः दो बिंदुओं के बीच की रेखा पर बिंदु है। कम से कम यह धारणा कि मैं एश्री प्रलेखन से प्राप्त कर रहा हूं (चौराहों का अर्थ असहमति नहीं है; एक शीर्ष पर स्पर्श का अर्थ है)।

क्या यह संभव है कि बिंदु एक मल्टीप्लगॉन NS ST_Intersects के बाउंडिंग बॉक्स के भीतर आता है, जबकि मल्टीप्लगॉन की बाउंडिंग ज्यामिति ले रही है, जबकि अन्य केवल फीचर के सटीक निर्देशांक पर क्या झूठ बोल रहे हैं? क्या आप QGIS में पॉइंट / पॉली का स्क्रीन कैप्चर पोस्ट कर सकते हैं?
